Bryan Johnson, the eccentric biohacker who has poured over $2 million into his quest to "live forever," has unveiled the jaw-dropping results of his latest experiment.

Johnson, now in his late 40s, has long been on a mission to reverse aging through strict diets, experimental medical treatments, and even controversial methods like using his son’s blood.

His lifestyle has already produced startling claims—including the "heart of 37-year-old" and the "lung capacity of an 18-year-old."

Now, with hyperbaric oxygen therapy, Johnson says he has reached another breakthrough in his radical longevity project.


Hyperbaric oxygen therapy involves breathing pure oxygen in a pressurized chamber, allowing the body to absorb significantly more oxygen than normal.

This treatment is known to help with wound healing, infections, and other health issues, but Johnson claims its potential goes far beyond that.

Over 90 days, he completed 60 sessions, each lasting 90 minutes, documenting every step of the way on his YouTube channel. The results, he says, are nothing short of transformative.

Among the most striking outcomes, Johnson reported a 300% growth in blood vessels and a 1000% increase in akkermansia, a gut bacteria tied to better metabolism and overall health.

His Alzheimer’s risk marker also dropped by 28%, suggesting a significant boost in long-term cognitive health.


Even more, his skin showed visible rejuvenation, with UV damage improving by around 10% across his body.

For someone determined to extend his life indefinitely, these changes represent measurable progress toward his controversial goal.

Perhaps most sensational of all was the data on Johnson’s telomeres, the protective caps on chromosomes that indicate biological aging.

His telomere results matched those of a ten-year-old—an astonishing claim that suggests his biology is decades younger than his chronological age.

Johnson believes this proves hyperbaric oxygen therapy can reset critical markers of health and longevity. While scientists remain cautious about interpreting these findings, Johnson continues to position himself as a test subject in the most ambitious anti-aging experiment in the world.

But not all of his methods have been celebrated. Johnson previously sparked outrage when he publicly shared "erection data" comparing himself with his son, Talmage.

The strange dataset tracked sleep efficiency, erection quality, number of erection episodes, and total duration.

Johnson scored higher in erection quality at 94 compared to his son’s 90, though he admitted Talmage outperformed him in frequency.

Despite the backlash, Johnson remains undeterred, pushing forward with bold claims and controversial transparency.

His critics argue that his obsession with reversing aging borders on unethical science, while supporters view him as a pioneer in human longevity.

Whether or not hyperbaric oxygen therapy truly holds the key to "living forever," Johnson’s experiments continue to captivate millions online.

At the very least, his data-driven journey is forcing people to ask just how far science can—or should—go in the fight against aging.
