Bryan Johnson, the millionaire entrepreneur who has famously dedicated his life—and a staggering $2 million a year—to “living forever,” has just dropped the results of his latest radical experiment. This time, it’s hyperbaric oxygen therapy. And if his claims hold any truth, he might be a few breaths closer to reversing time itself.
The 46-year-old biohacker, known for turning his own body into a high-tech laboratory, underwent 60 intense oxygen therapy sessions over 90 days. Each session involved breathing pure oxygen in a high-pressure chamber for 90 minutes—an experience designed to supercharge the body’s absorption of oxygen and accelerate healing and regeneration.
The results, according to Johnson, are nothing short of staggering.
A Breath of Eternal Youth?
In a video shared on his YouTube channel, Johnson details how his experiment led to a 300% growth in blood vessels and a 1000% increase in akkermansia, a gut microbe strongly linked to metabolic and digestive health. He also claimed a 28% drop in biomarkers linked to Alzheimer’s disease, improved skin quality, and reduced UV skin damage by 10%.
But the headline figure? His telomeres—the biological caps on the ends of chromosomes that typically shrink with age—apparently now resemble those of a 10-year-old. Telomeres are widely considered key indicators of biological age, and Johnson believes this reversal is clear evidence that his body is “aging backward.”
From Son’s Blood to Oxygen Pods: What Won’t He Try?
This isn’t Johnson’s first foray into experimental immortality. He’s previously gone viral for his unconventional anti-aging routines, including receiving plasma transfusions from his teenage son and tracking intimate metrics like erection quality during sleep (yes, really).
In one eyebrow-raising episode, Johnson published comparative data between himself and his son, Talmage, showcasing their sleep efficiency and nocturnal performance. While critics slammed the move as excessive and invasive, Johnson argued it was all part of his unwavering commitment to data-driven longevity.
What’s the Point of It All?
For Johnson, this isn’t a gimmick. It’s a deeply personal mission—a quest to hack the code of aging and shift how humanity understands health, lifespan, and time. His experiments spark both admiration and disbelief: is he unlocking future medicine, or just indulging in Silicon Valley's most expensive midlife crisis?
“People don’t understand how rigged the aging game is,” he once said. “But what if we could turn it on its head? What if death is just a problem we haven’t solved yet?”
Whether you view him as a visionary or a provocateur, Bryan Johnson continues to push the boundaries of what it means to be alive—and how long we can stay that way. As for oxygen therapy? For now, it might just be his most breathable bet in the race against time.

6/ My HBOT protocol in a glance
— Bryan Johnson (@bryan_johnson) March 18, 2025
+ Hard shell chamber from @hpotech_medical
+ 2 ATA
+ 90 minute sessions
+ 20 min breathing 100% oxygen. 5 min break. Repeat.
+ 60 sessions within 90 days.
The protocol is consistent with the most credible clinical studies up to date.

I've started a new longevity protocol: hyperbaric oxygen therapy (HBOT).

Here's what we know.
What we're doing.
And what we hope to achieve.
