Biohacker Bryan Johnson has sparked immense backlash after he measured the quality of his teenage son’s erections before comparing them to his own and sharing the results online.
Bryan, 47, has become infamous for his multi-million dollar quest to reverse his age, but his most recent experiment left many people on the web scratching their heads.
The mogul took to X, formerly Twitter, on Wednesday to announce that he gathered ‘nighttime erection data’ on his 19-year-old son, Talmage Johnson, and found that his ‘duration was two minutes longer than his.’
He even shared screenshots of data breaking down his and his son’s erections throughout the night, and social media users were extremely uncomfortable with him sharing his son’s personal information online.
‘Nighttime erection data from my 19-year-old son, @talmagejohnson_ , and me. His duration is two minutes longer than mine,’ he wrote.
‘Raise children to stand tall, be firm, and be upright.’
Immediately, his replies were flooded with messages from disturbed X users.
‘Next time I’m mad at my parents I’ll remember that they don’t measure my erections and publish the data to the public,’ one person replied.

‘If my father tracked my nightly b***rs, compared them to his own, publicly posted the data, and then TAGGED ME, I would absolutely kill myself,’ announced another.
Someone else added, ‘For the love of God, why would you post this on the internet publicly? I feel bad for your son.’
‘Legitimately the most insane thing I’ve ever read,’ a fourth tweet read, while a fifth simply said, ‘Too much information.’
‘This is weird man,’ a different user replied.
‘Did your son give you permission to share these? This is very sensitive and private information,’ asked someone else.
However, Talmage was quick to come to his father’s defense, reposting his tweet and adding, ‘I’m grateful for the way my dad has raised me.’
Earlier this month, Talmage explained on Instagram that he moved to California to live with his dad in high school.
Soon after, he said he started ‘fully committed’ to his dad’s ‘protocol,’ which involves implementing a ‘perfect’ diet, exercise routine, and sleep schedule.

They eat their last day of the meal at noon, stick to a 2,000-calorie vegan diet that includes broccoli, cauliflower, and walnuts, and gobbling down 80 vitamins and minerals a day
‘Now, I might just be the healthiest 19-year-old alive,’ he wrote.
He said he was taking a gap year from college to work at his dad’s company, Blueprint, and help build his dad’s ‘Don’t Die mission’ in an ‘effort to align humanity, the planet, AI, and maybe stop us all from accidentally self-destructing.’

Bryan also previously revealed he injected himself with his son’s blood in a bizarre attempt to de-age himself
Bryan previously revealed that he and his son wake up at 5am every day and go to bed at 8.30pm.

Back in 2023, he first spoke about tracking his erections at night, revealing at the time that he wears a small device on his penis while sleeping.
This measure of sexual function, he said, could help predict other health outcomes like cardiovascular fitness.
He has also revealed that he goes through shockwave therapy on his penis to get more erections that resemble a teenager’s; he believes this improves his pelvic floor function, leading to more erections.
