Cervical non-invasive vagus nerve stimulation (nVNS) has emerged as a practical neuromodulation approach with FDA-cleared indications in primary headache disorders, yet skepticism persists over whether transcutaneous stimulation can reliably engage vagal fibers or whether observed benefits reflect nonspecific cervical activation. Here, we synthesize converging anatomical, biophysical, physiological, and clinical evidence demonstrating that nVNS does, in fact, activate vagal pathways without surgical implantation. We first review cervical vagus anatomy and the biophysical basis for target engagement, including ultrasound-measured nerve depth and multi-scale computational models showing that clinically relevant stimulation can recruit predominantly large myelinated vagal fibers. We then integrate mechanistic evidence across complementary modalities: functional imaging consistently modulates canonical vagal projection sites (including brainstem nuclei), electrophysiology demonstrates peripheral vagal recruitment and centrally transmitted evoked responses, immune studies reveal reproducible suppression of pro-inflammatory cytokines consistent with cholinergic anti-inflammatory reflex engagement, and autonomic biomarkers show shifts toward increased parasympathetic tone. Finally, we contextualize these mechanistic findings with sham-controlled randomized trials in cluster headache and migraine, where nVNS repeatedly outperforms sham for acute and preventive outcomes with a favorable safety profile. Together, these independent lines of evidence form a coherent mechanistic fingerprint that is difficult to reconcile with placebo or superficial muscle stimulation accounts. We conclude that nVNS provides a credible, scalable means of accessing vagal neurophysiology and represents a clinically validated, paradigm-shifting advance in bioelectronic medicine.

Good morning. Lately, I’ve been listening to the “I Love Boosters” score when I need to focus at the office. The Tune-Yards-composed music is kooky, manic, and sort of makes my heart rate go up. I love it.
The “steroid olympics” were a circus—and a window into our culture
Testosterone. Methenolone. Nandrolone. Human growth hormone and EPO. Meldonium, modafinil, and mixed amphetamine salts. Clomiphene, anastrozole, levothyroxine, and liothyronine. Patches and capsules, creams and pills. A whole galaxy of steroids, metabolic modulators, and synthetic hormones coursing through the blood of a few dozen swimmers, sprinters, and weightlifters. And millions of dollars up for grabs for athletes who could break world records and usher in the age of superhumanity.
On Sunday, May 24, at a $50 million arena built in a casino parking lot in Las Vegas, I witnessed a libertarian thought experiment come to life. The inaugural Enhanced Games were the first sporting competition where participants were encouraged to take performance-enhancing drugs. The founders say they’re challenging dated sporting norms and helping to build a world where we can all live better, longer lives. Critics say the event is an embarrassment, that it glamorizes the use of dangerous substances and puts lives at risk.
The open-air venue was compact and decked out in bright blue, with a six-lane, 100-meter track down one side, a four-lane Olympic-length swimming pool down the other, and a weightlifting platform and stage at the front. You could see the golden façade of the Trump Hotel looming in the background. The scene had all the trappings of an NFL game, with the too-loud music and crowd work on the big screen—a “flex cam” gave the well-muscled an excuse to unveil their biceps. Between events, adverts flashed up for the line of performance products sold by Enhanced, the company behind the event: injectable peptides that supposedly support cellular energy and skin elasticity, daily supplement powders with names like “Stronger” and “Longer.”

Australian swimmer James Magnussen was the first athlete to sign up with Enhanced but hasn’t broken any world records. He finished last in his two events in Las Vegas.
The day started with the weightlifters, under the blazing sun. But by 4 p.m., only one of them had even attempted a world-record lift. Two had pulled out injured. Some athletes were competing without taking drugs because of the money on offer, and as the competition went on, they had the better of their enhanced peers: Hunter Amstrong, a 25-year-old American swimmer and triple Olympic medalist, won the backstroke by more than a second. In the men’s 100-meter sprint, the non-enhanced US athlete Fred Kerley romped to an easy victory. “Man, they gotta do better than that,” he said of his doped opponents in his post-race interview. “They need to train a little harder, get on that shit a little bit more.”
At the bar, bodybuilders swapped before-and-after pictures and talked about their stacks, and VCs and finance bros traded LinkedIn details. Lukas Lakutsin, a 6-foot-10, 354-pound Russian bodybuilder who was milling around the entrance to the VIP suites, initially told me he didn’t use any performance-enhancing drugs. Except testosterone replacement therapy, of course. But he didn’t think that really counted. “I’m almost 34 years old,” he said. “I need to do this to stay strong.”

Jeremy Sigal, an influencer and author, wore a USA tank top that showed off hugely muscled arms adorned with prison tattoos. He told me he was proudly natural, in both his health and his personal life. “I’ve got an exceptional credit score,” he said. He has written 12 books on marketing and leadership. Later, I looked up his most recent book online. It’s called Simp to Pimp: 10 Steps to Fix Why She’s Not Banging You and lists AI as a coauthor.
What I saw in Las Vegas probably wasn’t the future of sport. But it was a perfect encapsulation of our present moment, as Silicon Valley biohackers, alt-right looksmaxxers, Make America Healthy Again boosters, and longevity-obsessed scientists all vie to remake reality in their own image. For them, the Enhanced Games offered a glimpse of a future where medical advances push the human race to new heights, and where they never have to get old.
I’ve tracked Enhanced’s journey from a crazy idea scribbled on a napkin to a public company valued at $1.2 billion. Behind the scenes, there have been power struggles, life-changing victories, and moments of total farce. As I recently, finally, watched the games unfold, two questions bounced around my head: Were they right? And what does that mean for the rest of us?
In December 2022, the Australian entrepreneur Aron D’Souza flew to Miami to spend New Year’s Eve with his friend and mentor Peter Thiel. A decade earlier, D’Souza had helped Thiel orchestrate the lawsuit that bankrupted Gawker—a stunning revenge against the gossipy New York media blog that had outed him as gay. Now he was armed with a disruptive idea that he thought Thiel, the billionaire cofounder of PayPal and Palantir, would love. It was inspired by the buff bodies he’d been seeing at the gym, highlighting a disconnect between a workout culture where the use of steroids was an open secret and a sporting establishment where it was, at least on paper, an inviolable taboo.
His initial pitch was provocative and confrontational: a grand sporting event to rival the Olympic Games, where competitors could take any substance they wanted—their body, their choice. The first time I met D’Souza, in the spring of 2024, he had founded the company and attracted some initial investment but seemed obsessed with taking on the fat cats at the International Olympic Committee and reinventing sports (even though he didn’t seem to be a huge sports fan himself). On Enhanced’s Discord server, I found a folder full of memes with names like IOC Clowns.jpg. The whole thing felt very unserious.
That would change.
D’Souza told me that Thiel had previously introduced him to Christian Angermayer, a German biotech billionaire, who would come onboard at Enhanced. He’s funded clinical trials of psychedelics through his company Atai Life Sciences and is helping bring them into the medical mainstream as a treatment for depression and anxiety. Angermayer says he spotted an opportunity to do the same thing for steroids. What he really wants is to redefine medicine, he told me. Its focus has already changed from treating disease to trying to prevent it; actively enhancing people’s health, he says, is just the next logical step.
By early 2024, Angermayer had brought his own people into key roles. The team included Michael Sagner, an anti-aging expert and private doctor who works with many of Hollywood’s leading men, and Max Martin, who has the jawline and cheekbones of an Instagram looksmaxxing influencer and the boundless enthusiasm of a puppy. (He started his own enhancement program a few years ago, when he was just 27.) Sagner would head up Enhanced’s medical commission, making sure the games were safe for the athletes. It was Martin’s job to make sure they actually happened.
LEV RADIN/ZUMA PRESS WIRE VIA ALAMY
Tensions sparked as D’Souza’s freewheeling style clashed with the more sensible image that Sagner and others were now keen to present. “It was not just his personality and his abrasive way of talking,” Sagner told me recently. “Even when he was briefed on a scientific fact, he would just completely ignore it and say something outrageous.”
But the more outrageous D’Souza got, the more attention his idea received. In February 2024, James Magnussen, a retired Australian swimmer, became the organization’s first official athlete, and Enhanced promised to pay a million dollars to him, or anyone else, who could break the world record in the 50-meter freestyle.
The notion of a “steroid olympics,” as many have dubbed the Enhanced Games, had been kicking around for decades—for instance, in a Wired article from the early 2000s and an SNL sketch from the 1980s. Two things helped finally make the Enhanced Games a reality. First, in November 2024, Donald Trump was again elected president of the United States. The Biden administration had been actively hostile to the games, but the founders saw a more receptive political environment in Trump world. Not long after the election, Enhanced announced a new tranche of funding led by 1789 Capital, a venture capital firm whose partners include Donald Trump Jr.
And second, in February 2025, an enhanced swimmer finished the 50-meter freestyle faster than anyone in human history. It wasn’t Magnussen, though. He had been injecting himself with testosterone to grow muscle, plus a cocktail of peptides that aimed to speed up recovery—but his journey hadn’t quite worked the way he’d planned.
A combination of reputational issues (no pools wanted to host his training) and physical complications (the regimen did help him get stronger, but he packed on so much muscle that it slowed him down in the water) meant he watched from the sidelines as the Bulgarian-Greek swimmer Kristian Gkolomeev—who had finished fifth at the Paris Olympics in 2024—came in two-hundredths of a second under the record and won a million-dollar payout from Enhanced. The idea has always been that breaking records would effectively prove the legitimacy of this enhancement project: Look what we can do now.
SAEED RAHBARAN

Gkolomeev, though, had a different motivation for participating: “One successful year in the Enhanced Games and I could make as much as I would in almost 10 careers,” he told me not long after setting the new record (notably, wearing a kind of “supersuit” that’s been banned by World Aquatics since 2010). Enhanced was paying its athletes a regular salary, on top of any potential bonus. And he had a young family to support and feared that the four-year stretch to the next Olympics would be long and precarious.
In May 2025, with a world record in the bag and a friendly administration in the White House, Enhanced was ready to announce its first games: They’d take place in May 2026 at Resorts World in Las Vegas.
At the same time, D’Souza made another big reveal: Enhanced Performance Products, a line of supplements available for a monthly subscription. The Enhanced Games now seemed less like a sporting event and more like a loss leader for selling testosterone injections, GLP-1s, or a range of peptides that are claimed, with little scientific evidence, to improve sleep or skin elasticity. Perhaps it was all a brilliantly executed marketing stunt.
“The games themselves now seem almost secondary to what appears to be an online marketplace for hormones, peptides, and other performance-enhancing compounds,” says Astrid Kristine Bjørnebekk, a steroids expert at Oslo University Hospital. “From my perspective, this significantly changes the nature of the project. It is one thing to organize a closed sporting event built around controversial principles, but openly marketing and commercializing substances such as testosterone, hGH, GLP-1 drugs, peptides, and other pharmacological compounds is something else entirely.”
As the games approached, more athletes joined. Some were genuinely elite. The US sprinter Kerley—who is serving a two-year ban for missing three drug tests—had won silver in the 100 meters in the Tokyo Olympics and a bronze in Paris. Ben Proud, a British swimmer, had won silver at the Paris Olympics and dozens of medals at world and European championships and the Commonwealth Games. He had been mulling over joining the Enhanced Games ever since the idea first emerged, but the tipping point seemed to come when Gkolomeev’s record was announced.
Some participants, like Magnussen and another swimmer, Megan Romano, had been tempted out of retirement. Romano hadn’t swum competitively for almost a decade. Others were at the start of their careers but ready to cash in their chips and bid goodbye to Olympic dreams for a potential six-figure payday. The $1 million payouts were reserved for records in the two flagship events—the 50-meter freestyle and the 100-meter sprint—but winning any other event would mean a prize of $250,000, with an additional $250,000 bonus for setting a world record.
Athletes would get paid even if they just showed up and finished last—as much as $50,000. This is all on top of the salaries that stretched into six figures in some cases, making the payout from the games more than many athletes make in a year.
Sport’s governing bodies reacted to each new athlete announcement with fury. World Aquatics threatened to ban for life any athlete who participated in the games, even if they didn’t take any drugs. Enhanced responded with an $800 million antitrust lawsuit against the global swimming organization, the World Anti-Doping Agency, and USA Swimming, alleging misuse of monopoly power.
SAEED RAHBARAN
In November 2025, a court in New York dismissed the case. Three days later, D’Souza, the mind behind the entire project, was out. A notice on Enhanced’s website said he had “transitioned out of the company’s day-to-day operations.” Martin would take over as CEO. “The investors basically said we need someone a bit more serious,” Sagner told me. In conversations, execs at Enhanced played down any suggestion of a feud—D’Souza was simply the ideas man, with little interest in the day-to-day dreariness of actually running a company. (Enhanced spokesperson Chris Jones wrote in a statement that “there is no tension between Aron and Enhanced that I’m aware of.” D’Souza did not respond to a request for comment.)
I got the sense that Enhanced, in its new iteration as a pharmaceutical subscription company, was almost embarrassed by the games. When I visited enhanced.com a couple of months before the event, they had been relegated to a sub-heading on the home page. D’Souza’s showmanship had helped get attention for what was becoming a run-of-the-mill telehealth business like Hims & Hers—albeit one well timed to take advantage of a shifting regulatory landscape around peptides, which Robert F. Kennedy Jr., the US secretary of health and human services, has been pushing the FDA to approve despite a lack of evidence that they’re actually effective.
Sagner is still loosely involved with Enhanced, but he says the medical commission was not consulted before it launched its line of performance products. (Jones did not respond to a question regarding this claim.) Sagner is scathing about what he sees as the “hype” around peptides. “I can tell you already, peptides do nothing,” he says—with the exception of human growth hormone and GLP-1. “The peptides that people use, black-market peptides that they buy online—they do nothing. We have tested them; 80% of them contain nothing. It’s saline solution, salt water, and some of them are contaminated.”
At the end of January 2026, a group of around 40 swimmers, weightlifters, and sprinters arrived in Abu Dhabi to start their individualized enhancement “protocol,” as Enhanced calls it. Officially, they would be taking part in a clinical trial, pending approval by the Abu Dhabi government and overseen by Guido Pieles, a Qatar-based cardiologist who has taken over the reins of Enhanced’s medical commission from Sagner.
SAEED RAHBARAN
They would be allowed to choose only from a menu of specific FDA-approved drugs. Pieles broke them down into five categories: testosterone variants and growth hormones, which can both boost muscle mass; metabolic modulators that can tweak how the body burns fat; stimulants like Adderall to improve focus; and EPO, which can increase the amount of oxygen the blood is able to carry. While Enhanced’s team might recommend particular things, the athletes would have the final say on what they wanted to take, if anything. (As Oslo University’s Bjørnebekk points out, FDA approval “does not mean the substances are inherently safe, particularly not when used for enhancement purposes.”)
There would be regular blood tests, heart scans, and brain scans and access to the best training facilities money could buy. Pieles and others say the clinical trial will help inform the line of supplements Enhanced is offering consumers, but there’s actually very little overlap between the drugs the athletes were taking and the substances the company is currently selling.
Not long after they arrived in the Middle East, the athletes were awakened by the sound of explosions at a military base near their hotel. The US and Israel had struck Iran, and the Iranian regime was responding by peppering the region with missiles. “It wasn’t a pleasant situation,” says Andrii Govorov, the world record holder in the 50-meter butterfly, who a year earlier had become one of the first swimmers to join Enhanced. Govorov had some experience in these matters—back in Ukraine, he’d had a business selling cars that helped fund his swimming career, but he’d lost it after the Russian invasion.

Swimming, sprinting, and weightlifting were the focus of the first Enhanced Games but in many ways the sports were the sideshow.
The conflict exacerbated delays in getting approval for the clinical trial and sourcing the drugs, and as a result, what was supposed to be a 12-week enhancement protocol got cut down to eight weeks. The athletes didn’t actually start taking the drugs until toward the end of March. For those who had always been clean, that represented the irreversible crossing of a line. “The first injection was very emotional, very tricky to navigate,” says Proud. “For me, that was the day I went from the Ben Proud that I always knew to a new person.”
Proud was joined in the enhancement program by his girlfriend, Emily Barclay, who had swum at college level without ever appearing at a major international event; she was working as a swimming teacher at a school in England. After that first injection, they left Abu Dhabi and spent a few days in Dubai as they reckoned with what they had done. “I just couldn’t be around the team,” Proud says. “I wanted to be by myself and feel those feelings, because it is a big deal to make that step, and I felt it.”
Those feelings were soon forgotten, though, as the drugs kicked in. Proud says he had incredible energy, and a drive to train that he hadn’t experienced before. Shania Collins, an American sprinter, says she had “increased strength, increased recovery, and increased mental clarity at practice.” Sagner and several athletes admitted there were some side effects: acne and some swelling around the joints; unwanted hair growth for the women, unwanted hair loss for the men.
SAEED RAHBARAN
One thing the athletes wouldn’t talk about, though, is what drugs they were actually taking. They all had the same reason: not wanting to encourage copycats who might take enhancements without a doctor on hand to tailor programs to their needs.
The one exception was Thor Björnsson (testosterone, deca-durabolin, anastrozole, halotestin), a hulking Icelandic deadlifter and former World’s Strongest Man who played The Mountain on Game of Thrones. Björnsson first heard about the games on Joe Rogan’s podcast and was immediately interested. The rules for strongman competitions are somewhat less stringent than those for Olympic sports, though, and he actually had to reduce the number of substances he was taking to meet Enhanced’s FDA requirements.
SAEED RAHBARAN
There is some debate over how much doping some of the athletes were actually doing. In a conversation last year, Gkolomeev told me he’d only really been “microdosing,” and he confirmed that his 2026 enhancement program was largely the same. Sagner says the doses the athletes were taking were a fraction of the amounts some Olympic athletes had been caught using in the past. I heard that a few athletes had decided not to take steroids or growth hormones and were only using modafinil, a narcolepsy medication that’s thought to improve focus.
The day before the games, I asked Angermayer what it would mean if clean athletes like Kerley and Armstrong won their events—what impact it would have on Enhanced’s business model of using sports as a showcase for its line of performance products if the people using those products didn’t actually win anything. “I know what you mean, but mostly our business model is headlines to drive attention,” he said. “Any debate is good for us.”
In early May, Enhanced began trading on the New York Stock Exchange with an initial value of $1.2 billion.
That same week, it was finally go time. The athletes and coaches left Abu Dhabi and flew to Las Vegas, where they were put up in five-star luxury at the Conrad hotel inside Resorts World while they made their final preparations.
When I got there a few weeks later, toward the end of May, I found it jarring to see these hulking presences walking around the casino in their Enhanced sportswear, weaving their way through packs of half-drunk tourists, with slot machines flashing in the background and cigarette smoke hanging in the air. I had expected the games to be a bigger deal within the city itself, but they were just one of a thousand things happening in Vegas that weekend—drowned out by a series of BTS shows at the football stadium, by the Golden Knights in the NHL playoffs, by No Doubt’s residency at the Sphere.
If this was a sporting earthquake, it was one whose tremors were mainly being felt online, where bodybuilding influencers livestreamed to their followers on Kick and Twitch, and where thousands watched on YouTube and Rumble. (D’Souza once told me he’d had “every major sports broadcaster” vying for the rights; in the end, Enhanced struck an exclusive streaming deal with Roku in the US.)
SAEED RAHBARAN
On the morning of the games, Enhanced held a medical symposium that was supposed to provide a taste of the company’s long-term objectives. The first speaker was Bryan Johnson, the longevity-obsessed entrepreneur famous for plowing his personal fortune into wild attempts to reverse his aging: receiving transfusions of his teenage son’s plasma, measuring his nighttime erections, taking more than 100 supplement pills a day. He spends $2 million per year on all this, but he looked pale and vampiric as he delivered the slightly off-brand message that, really, the most important thing was getting a good night’s sleep: “You don’t need to chase IV infusions; you don’t need to chase crystals. You don’t really need to do much of anything.”
At 2 p.m., I took two escalators from the conference room down to the arena, where spectators were filtering in. Though it had cost $50 million, it had been constructed in just three and a half weeks, and it showed; on the media tour the previous day, there were still loose screws on the floor of the bleachers.
There were a few thousand seats in an open grandstand down one side, and two rows of VIP suites on the other. No tickets were sold, so it was a strange mix of invited guests, investors, and influencers, some of whom had reportedly been flown in from Los Angeles on a chartered jet. The rapper Tyga was the biggest name to grace the “blue carpet,” although I did also spot Fabio James, a Michael Jackson look-alike who has had surgery to make the resemblance even stronger. Rumors swirled that Peter Thiel might show up; they proved unfounded.
SAEED RAHBARAN
A few hours before the doors opened, journalists got a stern message from the organizers trying to bar us from interviewing guests. Still, I talked to a Cambridge professor who wanted to use Enhanced as a case study in innovation for his MBA students, a retired Brazilian swimmer with the Olympic rings tattooed on his forearm, and a biotech investor wearing an Enron hat. Proud’s family and friends were sheltered from the blazing sun in the shadow of the big screen.
D’Souza was nowhere to be seen. Nor was he really mentioned at all—not during the introductory press conference, where Martin was introduced as the “founder of the Enhanced Games,” nor during the event itself, where the athletes showered praise on Angermayer and Martin. But the tens of millions D’Souza had banked from the stock listing likely softened any blow. Plus, he’s already moved on to his next provocative venture: an AI-powered arbitration platform designed to scrutinize the work of journalists on behalf of the rich and powerful.
As the sun set behind the hills, casting the arena in soft gold light, there were still no world records. That and the wins for clean athletes seemed to put the whole Enhanced project in jeopardy—the knives were already being sharpened online. I asked the organizers whether this threatened the legitimacy of the project.
SAEED RAHBARAN
“Our response is that enhancements help athletes improve and, in some cases, break records. And yes, some non-enhanced athletes also won—because talent and ability also matter,” Enhanced’s Jones emailed last week. “Breaking world records is incredibly hard as the margin is infinitesimal, as we witnessed. Ignoring that 13 athletes some of whom 10 years later broke personal bests is disingenuous and selective reporting.”
Megan Romano was one of them, swimming faster in the 50-meter freestyle at 35 than she had at 22. And Emily Barclay knocked two seconds off her fastest time in the 100-meter freestyle, coming in second in that event and winning the 50-meter freestyle; she went home with a check for $375,000. “No one’s ever heard of this girl,” said Enhanced swim coach Brett Hawke afterwards. “She’s retired; she’s a nobody. She comes out tonight and swims a time that would have got a bronze medal in Paris.” For all the talk of “superhumanity” and pushing the boundaries of performance, making a 35-year-old feel 22 again is probably the perfect marketing message for the products Enhanced wants to sell.
SAEED RAHBARAN
Enhanced’s executives say people should take enhancements only with medical supervision, but price could be a barrier to heeding that advice. The battery of health tests the company was giving its athletes in the run-up to the games cost $25,000 per athlete per month. The drugs themselves start at $75 a month and go up toward $200. While Jones says the products “are in line with industry price points,” there were almost certainly people watching who saw the drug-altered physiques of athletes like Gkolomeev or Magnussen and decided to find cheaper, less safe alternatives on unlicensed websites.
“Many of these substances require medical supervision and prescriptions, and several are associated with potentially serious long-term health consequences,” says Bjørnebekk. “Presenting them in this lifestyle-oriented and commercial format risks normalizing use while downplaying the medical risks and uncertainties.”
SAEED RAHBARAN
Before the night was over, Gkolomeev again had the chance to right the Enhanced ship. The final event of the night was the men’s 50-meter freestyle swim. His 2025 time had been surpassed by the Australian swimmer Cam McEvoy (without a supersuit) at the China Swimming Open a couple of months before, so he needed to lose another two-hundredths of a second to beat the new record of 20.88 seconds.
Gkolomeev was wearing the same supersuit he’d used the previous year, and he’d shaved off his mustache for a little extra streamlining. But he messed up his start—doing four kicks instead of five—and was trailing Proud at the halfway mark. His long arms levered him forward, though, and he reached the wall in 20.81. The spectators were on their feet as “WORLD RECORD” flashed red on the big screen. Martin vaulted over the glass partition from the VIP suites, beaming, to embrace Gkolomeev. They had their record.
Or did they? Online, people shared screenshots from the video feed, purporting to show that the clock had stopped before Gkolomeev’s hand touched the pressure sensor at the end of the pool. An Enhanced spokesperson gave a statement to the Guardian dismissing this as “completely unfounded internet drivel.” But hey—live by the sword, die by the sword. It’s quite possible Gkolomeev didn’t care. He had another million in the bank.
It remains to be seen if it’ll work out so well for the other athletes. Enhanced organizers recently announced a prize of $10 million for anyone who can break Usain Bolt’s 100-meter world record in 2027. They are adamant that the games will happen again next year. If they don’t, dozens of sporting careers will be over, and the athletes will join the long list of victims of VC-backed disruption.
My personal prediction is that Enhanced will pivot away from the risk and uncertainty of a flagship event—the company’s valuation plunged by almost $800 million when markets opened after what was perceived as an underwhelming set of results in Vegas. I expect you’ll see individual stunts and challenges, tightly controlled and filmed for virality and probably featuring your favorite YouTubers—think Björnsson bench-pressing Jake Paul.
D’Souza’s initial idea has served its purpose by capturing the world’s attention. But that won’t necessarily translate into success either. Though the company has had plenty of hype over the last 12 months, SEC filings published as part of its stock exchange listing reveal that it generated only $2,755 in revenue from its enhancements business in the first three months of 2026. Would what happened in Vegas be enough to juice sales?
SAEED RAHBARAN
As the athletes gathered on the stage to receive their prizes, Martin took the microphone and addressed the crowd. “Enhanced is culture,” he said. “We are at the pulse of where the world is going.” On this, at least, he’s probably right. Testosterone replacement therapy is rapidly moving into the mainstream, and while the science may still not be there on peptides, they have certainly exploded in popularity in the two years since Enhanced launched. And there are undoubtedly more substances yet to be discovered that will promise to improve people’s lives, or at least hold their appearance in stasis. The enhanced age is upon us, whether we want it or not.
As the fireworks went off and the Killers closed out the event with “When You Were Young” (“Congratulations to … whoever deserves it,” said frontman Brandon Flowers), I wondered what that might mean for us mere mortals. Invoking Hunter S. Thompson’s Fear and Loathing in Las Vegas in a story about drugs and Las Vegas may be a cliché, but it struck me that fear played a big part in all of this. Fear of missing out. Fear of getting old. Fear of never making a dime on your life’s pursuit. Fear of waking up one morning and seeing your flabby, sunken face in the mirror while everyone around you shines and grins and thrives with white-toothed, alien smiles.
SAEED RAHBARAN
But the big problem with Enhanced’s vision of superhumanity is the question of who gets to join in. “People will be able to enhance themselves if they have enough money,” Sagner had told me the night before the games. The rest of us, I fear, will just have to function as normal human beings.

STAT+: The shortage of many medicines in the U.S. remains a ‘systemic’ problem, a new analysis finds
The number of prescription drug shortages in the U.S. fell by 23% last year, marking the second consecutive year of declines and the lowest level since 2017, according to a new analysis that otherwise found troubling signs about medicines that are in short supply.
For instance, the average drug shortage lasted 5.3 years, exceeding the 4.3 years seen in 2024 and greatly outpacing the average two-year shortage experienced in 2019. Moreover, nearly two-thirds of out-of-stock medicines were in short supply for more than three years, and 39% were unavailable for more than five years.
Meanwhile, the 75 drugs that were in short supply last year spanned 130 therapeutic categories, indicating that shortages affected a wide range of diseases and patient populations, according to the analysis by U.S. Pharmacopeia, an independent organization that develops standards for medicines.
First-in-Human Trial Reports Promising Dual Lassa–Rabies Vaccine Data
Researchers at the University of Maryland School of Medicine’s Center for Vaccine Development and Global Health (CVD) reported encouraging interim results from an early clinical trial that tested a new dual vaccine against Lassa fever and rabies. The study found the vaccine to be safe and induced immune responses against both the Lassa fever and rabies viruses (RB). There are currently no vaccines against Lassa fever on the market.
“This vaccine is designed to protect against two viruses of global health importance,” said study principal investigator Justin Ortiz, MD, MS, professor of medicine at UMSOM and vaccine researcher at CVD. “By combining targets into a single product, it could reduce the need for separate vaccination efforts and streamline delivery in settings where access is limited.”
Ortiz is first and corresponding author of the researchers’ published paper in Nature Medicine, titled “Adjuvanted inactivated rabies virus-vectored Lassa virus vaccine in healthy adults: a phase 1 trial,” in which they said, “If efficacy is confirmed, this combination vaccine could help protect populations from two priority pathogens and have a meaningful public health impact in regions where both diseases remain major threats.”
The World Health Organization has identified Lassa virus (LASV) as a public health threat in western Africa and made Lassa fever a priority disease for research. “Transmission occurs primarily through contact with food or household items contaminated by urine or feces from Mastomys rodents, although person-to-person spread can occur via exposure to bodily fluids or contaminated surfaces,” the investigators noted in their paper. Like Ebola, Lassa virus can trigger severe illness and periodic outbreaks in African nations.
Lassa virus infections occur in 300,000 people every year resulting in 5,000 deaths, according to figures cited by the authors, but these numbers are likely an underestimate due to limited surveillance. The disease is particularly dangerous in pregnancy with over 80% of late-term infections resulting in deaths to the mother or fetus. Additionally, regions where Lassa fever is common, such parts of Western and Sub-Saharan Africa, also have a high burden of rabies, with thousands of deaths annually, a disease that is almost always fatal once symptoms develop. The newly reported first-in-human trial was designed to evaluate the safety and immunogenicity of an adjuvanted inactivated rabies virus expressing the Lassa virus glycoprotein complex (GPC) on the surface of the virus. “Scientists at Thomas Jefferson University developed an inactivated rabies-vectored combination vaccine derived from an attenuated rabies strain, LASSARAB, expressing both the rabies glycoprotein and the LASV (Josiah strain) GPC,” the authors explained. “The RABV platform provides a well-established foundation for a dual-target vaccine.”
For the randomized, controlled trial 54 healthy adult volunteers from the Baltimore area were randomly assigned to receive different doses of LASSARAB, with an adjuvant or a licensed rabies vaccine control. Participants received two vaccine doses 28 days apart. Immune responses were studied through 61 days post-vaccination for an interim analysis. The results indicate that LASSARAB was safe with no serious adverse events (AEs) reported after vaccination. Additionally, the candidate vaccine induced rapid and robust antibody responses against both Lassa and rabies viruses when compared with the control, which only induced an immune response against rabies virus.
The study is ongoing, and vaccine safety and immune responses will be further studied through 394 days post-vaccination. “The final study report will be prepared after study completion and will include serious AEs and AEs of special interest through day 394, protocol-defined exploratory LASV and RABV antibody responses assessed at days 121 and 394, and any additional post hoc analyses, as applicable,” the team stated.
If the results indicate continued elevated immune responses from vaccination, researchers will proceed with more advanced clinical trials. Importantly, this investigational vaccine can be freeze-dried for storage, enabling distribution to areas of the world where it may be difficult to maintain cold chains. Importantly, this investigational vaccine can be freeze-dried for storage, enabling distribution to areas of the world where it may be difficult to maintain cold chains.
“These data support the feasibility of a bivalent rabies-vectored vaccine integrated into routine immunization for regions where cold-chain capacity is limited,” the team added.
“This study highlights CVD’s commitment to tackling diseases of global significance,” commented Stefan Kappe, PhD, director of the Center for Vaccine Development and Global Health and the Myron M. Levine Endowed Professor of Pediatrics. “LASSARAB not only targets diseases of concern but utilizes a platform that could make distribution attainable in the areas of the world that are most affected by these diseases.”
Added UMSOM dean Mark T. Gladwin, MD, “Climate change is causing Lassa fever to extend its reach far beyond its Nigerian and West African origins, putting an estimated 700 million people at risk worldwide. By 2070, the number of countries across Africa that will develop ecological conditions suitable for Lassa virus spread could drastically increase, so a vaccine to prevent this deadly infection is desperately needed.”
Last year, before results were available, the trial was highlighted by Nature Medicine in its 2025 feature, “Eleven clinical trials that will shape medicine in 2026,” which identified studies to watch based on their potential to address major unmet health needs.

Exposure to Moderate Air Pollution Raises Cardiovascular Disease Risk
Research from the University of Toronto shows long-term exposure to moderate air pollution increases a person’s risk of fatty build up in the blood vessels of the heart, which can lead to serious cardiovascular events like heart attack.
As reported in the journal Radiology, the study also showed that women were particularly badly affected and had an 81% increased risk for obstructive coronary artery disease if exposed to long-term air pollution.
“Even at exposure levels below current Canadian air quality standards, long-term air pollution was independently associated with more advanced coronary artery disease—suggesting current regulations may not be fully protective and that air pollution belongs alongside blood pressure, cholesterol and smoking as a modifiable cardiovascular risk factor,” said lead author Kate Hanneman, MD, associate professor at the University of Toronto, in a press statement.
The study included 11,128 people who underwent cardiac computed tomography (CT) scans who also had available data for air pollution exposure for around 10 years. The average age was 60 years and 52% were men.
In the cohort, median 10‑year exposures were 7.5 μg/m³ for PM2.5, a common measure of particulate air pollution and 13.4 ppb for nitrogen dioxide. These levels are relatively low compared with many historical and low‑/middle‑income settings but still above the latest World Health Organization guideline of 5 μg/m³ for PM2.5 and 5.3 ppb for nitrogen dioxide.
For each addition increment of PM2.5 (1 μg/m³) people in the study had had about 11% more calcium in their coronary arteries and 13% higher odds of having more atherosclerotic plaque. For each increment of nitrogen dioxide (1 ppb) small but measurable increases in calcium (aprx 1%) and plaque (about 4%) were seen in the coronary arteries of those exposed.
After taking into account age, risk factors, medicines, and other differences, each increment higher long‑term air pollution was linked to more severe, artery‑narrowing heart disease in women, but not in men. Each increment increase in PM2.5 was associated with an 80% higher chance of women having a dangerously narrowed coronary artery and each increase in nitrogen dioxide a 6% increased chance.
There was a similar trend in men, but it was not statistically significant after correcting for possible confounding factors.
“These findings add to the growing body of evidence identifying air pollution as a modifiable risk factor for atherosclerosis,” conclude the authors.
“Considering the epidemiologic data linking air pollution to cardiovascular events, these results reinforce the urgency of global public health initiatives aimed at improving air quality to reduce cardiovascular risk.”

First Phase III for Resected CRC ctDNA-Guided Therapy Shows Mixed Results
A highly anticipated Phase III clinical trial has delivered mixed results in testing whether a blood-based test for minimal residual disease (MRD) could guide early treatment for colorectal cancer recurrence (CRC).
Published in Nature Medicine, the randomized double-blind ALTAIR trial tested whether trifluridine/tipiracil (FTD/TPI) could improve outcomes in patients with resected stage I–IV CRC who tested positive for Natera’s Signatera circulating tumor DNA (ctDNA) test after completing standard therapy but had no radiographic evidence of disease. However, the Phase III study—a collaboration between Natera and several Japanese research institutions and hospitals—failed to meet its primary endpoint for investigator-assessed disease-free survival (DFS).
The findings represent the first completed randomized Phase III “treat-on-molecular-recurrence” (TOMR) trial in CRC and underscore both the promise and limitations of ctDNA-guided intervention strategies, highlighting both the promise and limitations of precision oncology.
A slice of the GALAXY
In the ALTAIR trail, researchers from the National Cancer Center Hospital East in Kashiwa, Kansai Medical University in Osaka, and NHO Osaka National Hospital evaluated a small subset of patients from a larger clinical trial called the CIRCULATE-Japan GALAXY study. Between June 2020 and June 2023, the GALAXY study enrolled 5,514 patients with resectable stage 0–IV CRC across 152 centers in Japan and Taiwan. The GALAXY cohort and other datasets have consistently shown that postoperative ctDNA positivity is associated with markedly increased recurrence risk. ALTAIR addressed the next critical question: whether intervening at the point of molecular relapse alters clinical outcomes.
Among the 1,104 patients who tested positive for ctDNA following surgery in the GALAXY study, 243 were included in the ALTAIR trial, where they were randomly assigned to either six months of FTD/TPI or a placebo. With a median DFS of 9.3 months in the FTD/TPI arm compared to 5.5 months with a placebo, there was a 21% decrease in the risk of recurrence (HR 0.79; 95% CI 0.60–1.05). The difference did not, however, reach statistical significance (P=0.107).
Although the primary endpoint was formally negative, several exploratory analyses suggested biologic activity. Six-month DFS was 70.5% with FTD/TPI versus 45.5% with placebo, indicating an early separation of the survival curves. The benefit, however, decreased over time, with recurrence curves converging by around 24 months—a trend that aligns more with delayed recurrence than with the lasting elimination of residual disease.
The strongest signal emerged in patients with resected oligometastatic stage IV disease. In this subgroup, FTD/TPI reduced the risk of recurrence or death by 47% (HR 0.53; P=0.012). Investigators noted that stage IV patients also had the highest baseline ctDNA burden, suggesting that molecular tumor load may influence responsiveness to MRD-directed therapy.
A post hoc blinded central radiology review also shifted the primary analysis into nominal statistical significance. After adjudication of discordant imaging events, median DFS was 9.2 months with FTD/TPI versus 5.5 months with placebo (HR 0.75; P=0.0406). However, because the analysis was exploratory and non-prespecified, investigators emphasized that it does not alter the trial’s formally negative outcome.
The ctDNA dynamics themselves proved highly prognostic. Patients achieving sustained ctDNA clearance had dramatically superior outcomes compared with those with transient or persistent positivity. In patients with sustained clearance, median DFS was not reached, while it was 11.8 months for those with transient clearance and only 4.4 months for patients with persistently detectable ctDNA.
Notably, spontaneous or transient ctDNA clearance occurred in a subset of placebo-treated patients, highlighting an emerging challenge in MRD-directed oncology: distinguishing biologically meaningful ctDNA positivity from low-level fluctuation or transient shedding.
Tomorrow’s TOMR
The study also raises important questions regarding treatment intensity in asymptomatic patients with molecular relapse alone. Toxicity with FTD/TPI was substantial. Grade ≥3 adverse events occurred in 73% of treated patients versus 3.3% with placebo, driven primarily by hematologic toxicity. Severe neutropenia occurred in 56.6% of patients receiving FTD/TPI, and more than one-third required dose reductions. Despite these toxicities, no treatment-related deaths or new safety signals were observed.
The ALTAIR data arrive amid broader uncertainty regarding ctDNA-guided treatment escalation in CRC. The recent DYNAMIC-III trial similarly failed to demonstrate improved recurrence-free survival with ctDNA-guided intensification in stage III disease. Together, the studies suggest that while ctDNA robustly identifies high-risk patients, translating that prognostic information into effective therapeutic intervention remains challenging.
Still, the investigators argue that ALTAIR establishes the feasibility of large-scale MRD-directed trials and provides a framework for future studies using more active regimens, including immunotherapy combinations or anti-angiogenic strategies.
For now, the trial reinforces a central emerging reality in precision oncology: detecting molecular recurrence is increasingly possible. Preventing clinical relapse after detection remains the more difficult task.

Digital Pathology and the NHS: Overcoming Barriers to a More Connected Future
As demand on National Health Service (NHS) U.K. pathology services continues to rise, the shift toward digital pathology has never been more critical. While the NHS 10 Year Plan identifies it as one of the system’s most transformative enablers, digital pathology adoption remains uneven. Damian Doherty, Editor in Chief of Inside Precision Medicine, sat down with Olga Colgan, PhD, strategic marketing director at Leica Biosystems, and Darren Treanor, MB BCh, PhD, consultant histopathologist at Leeds Teaching Hospitals NHS Trust, to explore the pressures facing today’s pathology departments, the transformative potential of digital workflows, and how collaborative partnerships are helping accelerate progress and unlock the full value of digital diagnostics.
Q: The NHS 10 Year Health Plan identifies digital pathology as one of three fundamental shifts, yet adoption remains limited. What are the key barriers?
Olga Colgan: Many pathology departments today are already stretched thin by managing growing workloads, which can make it difficult to pause and do a thorough workflow examination and consider process improvements. Transitioning to digital pathology requires an investment and openness to change. For decades, pathology has been optimized for glass slide review under a microscope, so moving to digital is not just a technology upgrade, but a cultural shift for laboratory staff and clinicians who value the familiarity and comfort of traditional methods.
Proper capital allocation and investment are critical to unlock the benefits of digital pathology. For example, information technology (IT) infrastructure must be capable of supporting high-resolution imaging, secure storage, and rapid sharing of thousands of slides. Regulatory needs must also be considered, as each lab must validate digital workflows to ensure appropriate compliance.
While these upfront hurdles can seem daunting, they lead to significant long-term gains. Digital workflows enable faster slide sharing, improve access to subspecialists, and ultimately improve turnaround times—delivering real benefits for both laboratory teams and patients eagerly waiting for critical results.
Q: What are the key benefits of digital pathology that make it such a crucial step for modernizing NHS pathology services—particularly in terms of workflow efficiency, diagnostic accuracy, and collaborative decision-making?
Colgan: Digital pathology is the quintessential modernization of a pathology laboratory, driving efficiencies in workflows, accuracy, and collaboration. Centralized digital storage provides instant access to prior cases and supports predictive analytics. Eliminating physical slides from the workflow after scanning reduces breakage risks and concerns, misidentification risks, along with space and storage needs.
Beyond efficiency gains, digital pathology unleashes the power of remote collaboration. The ability to share whole-slide images instantly means pathologists can quickly leverage remote expertise within their network, or obtain second opinions in minutes rather than days, accelerating diagnostic confidence and treatment decisions. It also extends expertise beyond geographic boundaries, removing the “postcode-lottery” and providing a basis for equity in pathology diagnostics. This enables rural or underserved regions to access pathologists without the delays, costs, and concerns of physical slide transport. This connectivity transforms pathology into a truly networked resource, ensuring that expertise is available whenever and wherever it’s needed, even after hours.
Further, although in the early stages of routine usage, artificial intelligence (AI) models can add another layer of support by bringing greater quantification and reproducibility to slide analysis, highlighting subtle patterns or abnormalities that may be difficult to identify by eye. Effectively, AI can act as a second set of eyes to further build diagnostic confidence and augment—rather than replace—pathologist review.
Q: How are companies like Leica Biosystems supporting NHS trusts in overcoming digital pathology adoption challenges?
Colgan: It starts with listening. We understand that every laboratory and every pathology department has unique workflows, bottlenecks, and priorities, so our first step is a conversation and analysis to identify those needs and design a tailored roadmap for transformation. This isn’t just about technology; it’s about creating solutions that make the pathology workloads more sustainable, especially at a time when the profession faces significant workforce shortages.
Leica Biosystems partners with labs to deliver systems that meet their demands today, while anticipating future growth and scalability. A great example is Leeds Teaching Hospital and the National Pathology Imaging Co-operative. Combined, they make up the largest national integrated digital pathology network in Europe for routine diagnostics—a milestone that demonstrates what’s possible when technology and collaboration come together. The Leeds Guide to Digital Pathology, volume one and volume two, is packed with practical tips and pragmatic approaches to support successful digital pathology adoption.
Q: What influenced Leeds Teaching Hospital to adopt digital pathology, and what transformation have you experienced?
Darren Treanor: We’ve been involved with digital pathology since the very early days of the technology, and it has become the essential foundation of our teaching and research work at the University of Leeds. We had taken a cautious approach to clinical adoption until we were convinced that the technology was ready—both in terms of clinical safety and technical readiness—and we could ensure that it worked and was safe.
We decided that the threshold for adoption for clinical use was reached in 2015, when we established that the clinical safety was acceptable and that the scanners and viewing software were fit for purpose and would not slow us down. Working in partnership with Leica Biosystems, we adopted a phased approach to 100% digital scanning, starting with a “meaningful pilot” with our four breast pathology colleagues. This group was the most pro-digital in the department and, being located in a separate building, had experienced frustrating delays in the delivery of glass slides between the main lab and their offices. They actively pursued us to “go digital.” The pilot with them was critical for us in planning the laboratory and clinical workflow reconfigurations needed to go digital and, importantly, developing a verification and validation process that allowed us to transition from glass to digital slides while maintaining safety. This process became the foundation of the U.K. Royal College of Pathologists guidelines for digital pathology, which have been adopted in many other countries as well.
We then looked toward the further summit of “100% digital” and took a phased approach, starting with immunohistochemistry (IHC). As a separate part of the lab, this activity could be separately digitized. With digital review of IHC being a lower-risk activity clinically, it allowed us to introduce the rest of our over 40 pathology consultants to the idea of diagnosis on a digital image. Once that was completed, we moved in one final big step to 100% digital scanning, reaching that milestone on a summer’s day in 2018.
Q: What lessons can other NHS trusts learn from your digital transformation journey, and what should be considered as they examine their current workflows?
Treanor: Because of our academic background and partnership with Leica Biosystems, we were very keen to share our experiences of going digital and how to do it. Too many deployments would talk of the great success in using whole-slide imaging, but gloss over the challenges and effort involved in getting there.
We wrote the Leeds guides to provide really simple general-purpose assistance to other labs that are new to digital pathology and didn’t have the benefit of in-house expertise yet.
Looking back, being early adopters, we had the unique challenge of being one of the first centers to go fully digital and pave the way at a time when scanners, displays, and software were just good enough, and the combined global experience of digital pathology was low. We have run many workshops to share our experiences, and it has been interesting to see how the field has evolved in recent times and how much easier it is now to go digital. There are far fewer “unknowns” when going digital now, and modern scanners and workflows are significantly better. For example, our current setup has a very smooth transition from H&E [hematoxylin and eosin] stainer to scanner, which saves a lot of time in the lab and removes a major obstacle to lab operation that we had to work around in the early years. In our early workshops, a deployment was often a multi-year project with a lot of uncertainty and need for a lot of preparatory work; nowadays, labs are much more digital-ready, the timelines are much shorter, and success rates are much higher!
