Neuroscientist Andrew Huberman Claims ‘All of Hollywood’ Is On Retatrutide

Popular neuroscientist Andrew Huberman has sparked discussion after claiming that celebrities across the entertainment industry have embraced retatrutide, the latest generation of weight management treatments.

In a series of posts on social media platform X, Huberman outlined what he describes as a predictable pattern in its adoption.

“All the celebs now getting that retrutatide look,” Huberman wrote to his followers. “If you want to know what will be massive on legal RX market 2 years ahead in the fat loss, muscle, vitality space… it always goes from bodybuilding (GH, TRT, GLPs, Retra.) to Hollywood to mainstr eam. EVERY TIME. Since the 80s.”

   

The Stanford professor described a consistent trend where compounds first gain traction in bodybuilding circles before making their way to celebrity circles and eventually becoming widely prescribed.

When asked to describe the physical appearance associated with retatrutide use, Huberman offered his assessment: “Thinner in face, tan, smooth sorta ‘tanned, underfed nak ed mole rat’ ish.”

Huberman clarified that he was not endorsing these medications and emphasized the importance of medical supervision.

“I’m not suggesting any of these. Talk to your MD, and whatever you do, don’t take ‘just for research purposes peptides’ the low level LPS is no bueno and many are fake,” he warned. “But the trend described above is so consistent. Chicken breast and broccoli be damned.”

Huberman’s observation about the adoption pattern has proven prescient in the past. Growth hormone, testosterone replacement therapy, and earlier GLP-1s all followed similar trajectories from niche bodybuilding use to celebrity adoption and eventually medical application.

When one follower mentioned that high school students were already using these medications to get lean, Huberman responded with concern: “Yikes.”

Another commenter asked whether Huberman was suggesting people could simply train with basic equipment and eat whole foods instead. “Hey @hubermanlab can I just throw a kettlebell around and eat real food? I can’t keep up with all these kids,” they wrote.

Huberman’s response was straightforward: “Yes.”

The neuroscientist also addressed speculation about financial interests, denying any investment in pharma companies when directly questioned about shareholdings.

The treatment Huberman references represents the new advancement in weight management technology. Unlike earlier GLP-1s such as semaglutide and tirzepatide, retatrutide appears to offer additional benefits that have captured attention far beyond medical weight loss programs.

Dr. Mike Israetel has become an outspoken advocate for retatrutide. During a recent appearance on the Trensparent podcast with Nyle Nayga, Israetel shared his enthusiasm for the compound, which he now uses personally.

“Tirzepatide is already a god molecule. Like, it’s amazing. I have nothing about it I don’t like. Retatrutide is like magic magic juice,” Israetel said.

According to Israetel, retatrutide offers a range of health benefits that extend well beyond simple appetite suppression.

He said, “It does like 10 other things for your health and longevity. It sensitizes you to muscle growth more. It controls your appetite like a turn dial. It reduces whole body systemic inflammation. It reduces neural inflammation. It pulls out your intra-abdominal fat. Retatrutide specifically zaps liver fat like nothing they’ve ever tested. It’s a health elixir, period.”

In a conversation with Jack Neel, Israetel described the medication’s impact on body composition with remarkable efficiency. “You could just lose like four pounds of fat a week. Unbelievable, right? And it’ll be amazing and you feel great because dieting really wears you down and with retatrutide it doesn’t really do that, which is just totally mind-blowing.”

The mechanism behind these results involves both appetite suppression and metabolic enhancement, creating what proponents describe as a dual-action approach that produces significant changes without the typical discomfort associated with traditional calorie restriction.

Israetel, who currently uses tirzepatide at 7.5 milligrams per week, explained that he experiences minimal negative effects. “I probably get better nausea from splitting it up, but honestly I just don’t get nausea. I get a little bit heartburn, but I take medications for that anyway.”

The discussion around these medications has extended beyond professional bodybuilders and Hollywood celebrities. Internet influencer Clavicular recently revealed that he credits retatrutide for maintaining a lean physique despite consuming fast food daily for the past year.

“I mean, I’m pretty much on fast food every day for the last year,” Clavicular stated when questioned about his eating habits.

When his co-host expressed surprise, noting that he projected a health-conscious image, the influencer disclosed his actual approach. “That’s going to be the furthest from the truth. For a while, it was the m*th. But now it’s like, more so just the IRL stuff, cardio max you know, I’d say. And what else? Retatrutide obviously, it’s a peptide. I’m basically on Ozempic.”

For Israetel personally, GLP-1s have provided a solution to a lifelong challenge. “My hunger knows no bounds. And so hunger control for me is the biggest unblock ever for prep,” he explained. His strategic approach involves year-round baseline usage with adjustments based on whether he’s gaining or losing weight.

 

While Israetel has pivoted his professional focus toward enhancement technologies after years of teaching traditional training principles, he maintains that informed adults should make their own decisions about their bodies.

“At the end of the day, it’s just about how adults want to look inside their own bodies. How do you want to look? We’re not telling you how you want to look,” he stated.
