Longevity Guru tested mushrooms – and became even more obsessed with his boners

by

The tech millionaire who has spent millions trying to reverse aging just discovered a new fountain of youth—and it’s turning heads for all the wrong reasons.

Bryan Johnson, the 47-year-old biohacking entrepreneur known for his extreme anti-aging protocols, recently took psilocybin mushrooms as part of what he’s calling “the most quantified psychedelic experience ever.”

But while he measured 249 biomarkers to track the trip’s effects on his body and brain, one particular outcome has dominated the conversation: his newfound fixation on spontaneous erections.

“Since the mushroom trip I’ve been having multiple spontaneous erections every day, something I haven’t experienced since childhood,” Johnson announced on X, burying the revelation beneath dozens of periods in a scroll-test of his followers’ commitment to “respecting others.”

The disclosure comes amid mounting controversy over Johnson’s transparency around his use of erectile enhancement medications. Critics have compared the situation to Lance Armstrong’s d*ping scandal, questioning whether Johnson adequately disclosed his daily Tadalafil (Cialis) regimen while promoting his “p*nis rejuvenation results.”

“I didn’t do a great job on that last post,” Johnson admitted on social media after commenters challenged the authenticity of his claimed improvements. He clarified that while he takes daily erectile dysfunction medication, his nighttime erections improved by 34% independently of the pharmaceutical intervention.

Now, Johnson attributes his post-mushroom erectile enthusiasm to reduced “cognitive inhibition,” increased “parasympathetic tone,” and elevated “brain entropy”—all leading to what he describes as “a more flexible, youthful nervous system.”

But the mushroom revelation represents more than just another eccentric chapter in Johnson’s quest for immortality. He’s proposing an entirely new framework for understanding psychedelic experiences, one that places equal emphasis on physical health markers alongside the traditional concepts of mindset and environment.

Johnson calls this third pillar “bodyset.”

“Psychedelics don’t land on a blank canvas,” Johnson explained in a detailed post. “They interact with the autonomic nervous system, inflammatory load, metabolic stability, sleep quality, hormonal environment, and overall physiological resilience of the person taking them.”

His theory suggests that pre-existing biomarkers could predict whether someone experiences insight and bliss or anxiety and dysregulation during a psychedelic journey. By measuring everything from cortisol levels to heart rate variability before his psilocybin experience, Johnson hopes to map the “foundational physiological patterns” that produce optimal trips.

The effects, he reports, have been profound. “I’ve felt kid-like excitement all week,” Johnson wrote. “That low-hum vibration, the tickle in the body, the thrilling anticipation. What you feel right before your first kiss.”

He claims his brain data shows his default mode network—the system responsible for rigid thinking and “boring adult mode”—remains inhibited. “My brain patterns show a higher entropy state: neuroplastic, open, flexible, creative, and exploratory.”

One follower noted that Johnson’s posting style changed dramatically after the mushroom trip. “Feels much smoother falling off my finger tips,” Johnson responded.

The longevity guru’s broader regimen includes waking at 5 a.m., consuming his last meal by noon, and sleeping by 8:30 p.m. He’s previously made headlines for injecting Botox into his p*nis (claiming it increases length by one centimeter) and undergoing plasma exchanges with both his 19-year-old son and 71-year-old father.

Johnson defends his Tadalafil use as a “longevity intervention,” citing research suggesting it reduces mortality risk by 34%, heart disease risk by 27%, stroke risk by 34%, and dementia risk by 32%. “Men, if you’re not performing how you’d like, there are many paths to improvement,” he stated. “There’s no shame in this and in fact will make you more of a man to address it head on.”

He also emphasizes that nighttime erections—which occur in both men and women—are “one of the strongest predictors of overall health.”

Health experts remain divided. Some praise Johnson’s openness about stigmatized men’s health issues, while others question whether concurrent medications make it scientifically sound to claim independent benefits from other treatments.

For Johnson, who describes feeling “legitimate hope for the human race” and experiencing emotions he hasn’t felt in 15-20 years, the mushroom experiment represents a breakthrough. “As an adult, you kind of stop believing things are possible,” he reflected.
