Bryan Johnson has turned his life into a £1.6million-a-year experiment in a bid to live forever.
The tech mogul obsessively tracks his body through what he has dubbed ‘Project Blueprint’ and even claims to have wound his “biological clock” back.
His bid to “live forever” was even the feature of a Netflix documentary.
The 47-year-old, who made his fortune from payments firm Braintree, sticks to an incredibly strict diet, piles of supplements, and a daily routine shaped by relentless tests and scans.
But he’s also broken the internet with his jaw-dropping stunts – from swapping blood plasma with his teenage son and dad to monitoring erections and even bragging about his partner’s “top 1%” vagina.
Here, the Daily Star rounds up the wackiest bits:

Blood plasma exchanges
In a “tri-generational” swap, Johnson received plasma infusions from his teenage son Talmage and donated his own to his dad Richard. At a clinic in Texas, the three underwent transfusions and saw the youngest and oldest members give up a litre of their blood.
This was then separated into various parts; plasma, platelets and red and white blood cells. All of this was then swapped with the middleman in a bid to freshen up old blood with new, repair damage and help reverse the ageing process.
Johnson also went through a phase of injecting his offspring’s blood into his body. He eventually stopped the treatments after finding no “detectable benefits”.

Tracking son’s erection
To monitor his cardiovascular health and sexual vitality, Johnson uses a wearable device to track the frequency and duration of his erections while sleeping.
He has also been measuring his 19-year-old son’s erections and comparing them to his own. He turned heads on X (formerly Twitter) when he posted the pair’s “nighttime erection data”. It showed Talmage’s “duration was two minutes longer”. Along with the screenshot of the data, Johnson wrote: “Nighttime 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 testing
The tech billionaire undergoes regular testing to measure the speed and health of his sperm, aiming to maintain the fertility levels of a much younger man. He also claims to have got rid of 95% of microplastics from his semen by using dry saunas every day for 20 minutes while applying an ice pack to his groin area.
The concentration of microplastics in his ejaculate dropped from 165 particles per milliliter in November 2024 to 20 particles per milliliter in July 2025, he revealed on X.
“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.
Vagina longevity claims
Johnson stunned fans this week 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.”
But 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.” He then told followers: “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.”
The “blueprint” diet
He eats exactly 1,977 calories daily, consisting of a strict vegan diet including a “Green Giant” drink and “Super Veggie” bowl, finishing his final meal of the day by 11:00 AM.
Johnson also takes over a hundred pills every day, ranging from common vitamins to prescription medications like metformin, which is traditionally used for diabetes but studied for anti-ageing.
Bonkers beauty routine
Sharing his strict daily beauty regime, Johnson wrote on X: “My day begins when I go to bed, sleep is my number one priority.
“I’m asleep by 8.30pm and I naturally wake around 5am.” Johnson then blasts himself with a “10,000 lux light” straight into his eyes for three to four minutes before applying a “hair serum” which he massages into his bonce.
After these beauty applications, Johnson meditates before making himself a supplement drink packed full of nutrients. Then it’s time for a work out, which he does for up to 90 minutes while listening to audiobooks and podcasts.

“On the weekends, I’ll play pickleball, ride a bike and hang out with friends,” added Johnson. “For breakfast I’ll have Blueprint Longevity Protein powder, berry nut mix, collagen peptides mixed with extra virgin olive oil and a few dozen pills.”
A post-breakfast shock therapy session is followed by a 10 minute stroll to get some sunlight. Around 8am Johnson starts his working day, which he does at his desk “while always maintaining the proper posture”, according to the Daily Star.
At 9am Johnson tucks into his second meal of the day, “usually a mixture of lentils, broccoli, cauliflower, mushrooms, hemp seeds, garlic and ginger”. Then it’s back to work, where every half an hour, the influencer spends five minutes “doing some sort of light exercise”.
He takes over a hundred pills every day
At 11am, Johnson eats his third and final meal of the day “which will be some combination of veggies, nuts, seeds and berries. My total calorific intake per day is 2,250”.
After more work punctuated by short periods of exercise, Johnson stops drinking his “mineralised liquids” at 4pm in order to prevent a toilet trip during his slumber. When 7.30pm hits, it’s time to “wind down”, which Johnson achieves by reading a book or spending time with family.
When it’s time to sleep, the influencer brags that he falls asleep “one to three minutes” after putting his head on the pillow. “And then I get to do it all again tomorrow,” he wrote.
Magic mushroom
Johnson took five grams of magic mushrooms as part of an experiment and told fans afterwards: “I’m just so happy to be alive.” He said that the experiment was to test 240 biomarkers to explore the affects of the hallucinogenic drugs on longevity. Johnson said on X: “We’re casting this really wide net of can we catch anything that demonstrates some kind of rejuvenation or longevity affect?”
His partner Kate Tolo took over his phone while he was high on the drug and updated his social media followers on the affects of the “hero dose”, which he mixed with orange juice and downed live on X. She documented his trip on the social media platform, where she told fans after an hour: “Sense of time is definitely warped.

“He thinks more time has passed than it has. Thinks he has peaked.
“Visual hallucinations are happening – my face and the trees ‘are alive’ and moving. As I am typing this he started giggling.
“He’s having a fantastic time.”

After getting his phone back, Johnson wrote on X: “Hey all, I’m just so happy to be alive.” He later added: “Yes, this trip changed me.
“Probably not as you’d expect. People assume I am fearful of death.
“I’m not. In my darkest days of depression, I reconciled with death.
“Need a few days to collect my thoughts. Will share more soon.”
Reversed ageing
Johnson took to X in yet another weird brag, this one about his telomeres – DNA protein structures found at the ends of chromosomes. His post read: “My telomeres say I’m 10 years old.
“They are regenerated at the vibrancy of a 12 year old. Data: Telomeres: 10.27 kilobases; telomerase activity: 7.7%
“Telomeres are like shoelace tips on your DNA, protecting your chromosomes every time your cells divide. Telomerase is the enzyme that maintains and restores telomere length with each cell division.

“Short telomeres = old, damaged cells.Long telomeres = youth, repair, longevity. Why it matters: Lower biological age, slower cellular aging, preserved genomic integrity, resistance to entropy
“Data sources: My telomere biological age is 10 years, based on a database of 15,000 other participants who took the test. Validated by comparing to a cohort of 12,230 participants (age between 20-100 years old: 2.5th-97.5th percentiles) from 6 countries.
“Note: 12-months average 12.07 kb, parallel test from a different provider 11.4 kb.” A number of graphs and tables were attached to the post, evidently supporting the outrageous claim, according to the Daily Star.
