Biohacker spending $2 million per year to reverse age reveals how he 'brought back his 22-year-old penis'

Entrepreneur and ambitious biohacker Bryan Johnson has revealed a new update on the state of his manhood — after spending $2 million (£1.57 million) a year to 'de-age' his penis.

47-year-old Johnson has made headlines numerous times over the past year for his bold commitment to anti-aging, with techniques including receiving plasma transfusions from his son as well as following a strict diet and exercise routine.

But all of this pales in comparison to his latest attempts to restore his prized manhood to optimal function.

And it would seem that his plan is working.

Last year, he claimed on social media that his erections were previously better than those of an average 18-year-old. The admission sparked interest, for obvious reasons, and Johnson has now committed to sharing regular updates about what's going on downstairs, whether we like it or not.

He would raise eyebrows earlier this year after posting a public comparison between himself and 19-year-old son Talmage Johnson's erections on social media, revealing the results of their recent 'erection test' in a series of bonkers X posts.

"Nighttime erection data from my 19-year-old son, Talmage Johnson, and me," Johnson wrote. "His duration is two minutes longer than mine."

Understandably, readers were confused by Johnson's decision to share such intimate details about not only his own penis function, but that of his son's as well.

Undeterred by the reaction to his oversharing, Johnson has made sure we're all aware about how one goes about lowering their erection age (should you wish to just that), which includes semen analysis, measuring his erections with a specialised device - called the Adam Sensor erection tracker -, and blood flow testing.

Johnson also revealed that he had in the past had little Johnson zapped with electric shocks — although we don't recommend you try this at home.

Explaining why he believes this is important, Johnson claimed on his website that men with experience erection problems are '70% more likely to die early'.

He went on to add that erection issues supposedly show up around '5 years before heart disease does'.

Johnson's claims are also backed up by numerous studies, with a study published in the The Journal of Sexual Medicine backing the erectile dysfunction claims up.

Which is fair enough, but I doubt most of us have the time or the means to be meticulously measuring our manhoods and analysing the results.

Speaking about his penis crusade in a recent interview with MailOnline, Johnson further doubled down on his decision, adding that both men and women should be paying attention.

"It turns out that — this is true for both men and women — that a man’s night-time erections and a woman’s night-time erections – the clitoris engorging — is one of the most important biomarkers of anything about our entire body," he said.
