Bryan Johnson spends millions every year on trying to reverse the ageing process, sort of like a modern day King Knut trying to turn back the tides
Bryan Johnson is perhaps the weirdest internet celebrity at out there at the miunte. The tech mogul plans to live forever as he invests millions into his strict regime of dieting and medical tests.
In his latest stunt, the biohacking eccentric this week announced he had “cloned himself” as a baby so that he could harvest its organs, naturally. On Twitter, he proudly proclaimed: “With this clone, I can become my own blood boy, test therapies on the clone, grow organs for transplantation, develop new treatments, and inject young cells.”
A lot of people argued underneath the post that it was “evil” for Bryan to raise a sentient human merely to test on. While we at the Daily Star aren’t going to get dragged into the reeds about the ethics and rights of clones, we can’t help but think it’s all a little bit weird.
What’s more – cloning himself as a newborn isn’t even the weirdest thing Bryan has done to try and push back the tides of time. Here we look at Bryan’s odd oeuvre:
Weird stuff with his son’s blood
First up – he used to vampirically inject his own teenage son’s blood because he thought it’d keep him young. Remember when a glass of shiraz and a boogie on Friday night made you feel young? Well forget about it, it’s all about taking your kids blood now – OK!
Thankfully, last year Bryan stopped this process because he said it “didn’t have any anti-ageing benefits” and Christmas at the Johnson’s became a bit more normal.
The U-turn didn’t last long though. Before you could say ‘have you tried having a lie down, mate?’ Bryan announced that, instead of taking his kid’s blood he was doing a “full plasma exchange”.
“1. Take out all blood from body,” he explained. “2. Separate plasma from blood. 3. Replace plasma with 5% albumin & IVIG. Here’s my bag of plasma. Who wants it?”
Night-time erections
Although Bryan hit the pause button on taking his son’s blood, the 19-year-old wasn’t out of the woods for long.
The obsessive tech millionaire soon turned his attention to the poor lad’s penis, announcing he had been comparing “night-time erection data” and posting it on Twitter.
The data showed his boy’s “duration was two minutes longer”. Along with the screenshot of the data, Johnson wrote: “Night-time erection data from my 19-year-old son, @talmagejohnson_ , and me.
“His duration is two minutes longer than mine. Raise children to stand tall, be firm, and be upright.”
Sperm quality monitoring
The tech tycoon regularly undergoes tests to assess the speed and health of his sperm, aiming to preserve the fertility levels of a significantly younger man. He also claims to have eliminated 95% of microplastics from his semen by spending 20 minutes daily in dry saunas while applying an ice pack to his groin area.
He revealed on X that the concentration of microplastics in his ejaculate plummeted from 165 particles per millilitre in November 2024 to just 20 particles per millilitre in July 2025.
“The therapy we think most responsible for this reduction is sauna as it also eliminated most environmental toxins in my body, including those linked to various plastics,” he wrote.
His girlfriend’s vagina
For all his foibles, you can’t argue that Bryan isn’t a romantic…sort of.
Johnson stunned fans earlier this year by publishing his partner’s ‘oral sex report’ and announcing that her vagina ranked in the top 1% based on medical testing for muscle tone and tissue health.
He said his girlfriend Kate Tolo’s sample was “dominated by the single most protective bacterial species a vagina can host”. He posted on X: “Just gave Kate oral sex. Goodnight everyone.” Awesome, man.
He later added: “This is her vaginal microbiome report. 100/100 score. Top 1% of all vaginas. Only about 25-30% of reproductive age women globally are L. crispatus-dominant, and ‘dominant’ usually means above 50%.
“Kate is at 98.7%. The lab found nothing bad to report. This is linked to lower risk of BV, UTIs, yeast infections, HPV persistence, HSV-2 and HIV acquisition, preterm birth, and improved IVF outcomes.
“A vaginal microbiome is downstream of everything: sleep, glucose control, stress, gut health, sexual health, immune function, what you eat, and what you put in it.”
