Bryan Johnson, the 47-year-old tech mogul turned biohacker, has recently taken his already-extreme quest to reverse ageing to the outer limits. In a post this week on X, Johnson announced he had completed his first total plasma exchange (TPE), a procedure that removes all the plasma in his body and replaces it with albumin. “The whole procedure took just under two hours,” Johnson told followers, as casually as if he’d just had a routine dental cleaning.
This latest experiment marks an escalation from Johnson’s previous plasma-swapping endeavours, which involved exchanging one litre of plasma with his teenage son (he admitted the process wasn’t particularly successful). Now, he’s going all-in, replacing his entire plasma volume in a bid to purge “toxins” from his body.
Johnson’s pursuit of eternal youth has become increasingly outlandish over the past two years. He claims to spend on various procedures and chemicals intended to rejuvenate everything from his “baby face” to his adolescent-style penis. His regimen includes over 100 daily pills, intravenous infusions, and constant monitoring of dozens of biomarkers. It’s a far cry from the “ancestral lifestyle” peddled by the likes of the now-disgraced Liver King, who kept his steroid use a secret.
The tech millionaire’s latest plasma purge represents a new frontier in his anti-ageing crusade. TPE is typically used to treat serious medical conditions such as autoimmune disorders or organ transplant complications. Its application as an elective anti-ageing therapy remains highly experimental, with little scientific evidence to support its efficacy. But since when has a lack of evidence stopped a Silicon Valley disruptor?
Johnson seems undeterred by the absence of proven benefits. He’s forging ahead with characteristic zeal, tracking an array of biomarkers before and after the treatments. “We completed a bunch of baseline measurements before this therapy including toxins but other things too such as speed of ageing, organ ages, microplastics and many other biomarkers,” he noted.
It’s easy to dismiss Johnson’s exploits as the indulgences of an eccentric millionaire with too much time and money on his hands. His quixotic quest to achieve immortality through hyper-aggressive medical interventions can seem absurd, even darkly comical. Yet there’s an argument to be made that we need someone like him to push the boundaries of what’s possible in human longevity research.

I think I’d rather have plasma exchange than Covid shots.
With Covid you can base your behaviour on the risk of getting it. While ageing is coming for everyone.
I agree with the author. Individuals are free (or should be) to pursue whatever means of seeking to slow down the aging process they wish, and if Johnson wants to subject himself to these procedures – with potential benefits in terms of knowledge gained for the rest of us – i don’t see any harm. (Not sure about involving his son in the process, however.)
In the end, it will just be a slowing-down, and i don’t see how it could be turned into a defeat of the inevitable: at some point, he’s going to die. The question i ask myself is: will he consider his efforts to be worth it, given that the effects upon his physical and mental state are unknown?
I’d like to stay fit and healthy enough to live past 100, just by taking normal steps to do so. I think beyond that point, i’ll be content for my atoms to return to the universe, knowing i’ve lived a full and enjoyable life. That seems to me to be our natural state; the psychological effects of changing that are unmeasurable. To give one example: Shakespeare delved into the human condition as fully as any human has done so. His legacy is as profound as anyone could wish. Would that still be the case if he’d found a way of still being ‘alive’ into the modern era?
We can leave a legacy in terms of the passing on of our DNA and cultural artefacts, including the influence we’ve had with the people who remain. Any change to that status would, i think, have negative cultural effects.
Your molecules are all replaced something like every 6 months. So everyone has a new body. It’s just that the photocopier is making the picture a little fuzzy after a while.
How much fun can this guy really be having if, instead of going out and partying, he sits around eating pills and having plasma replacements?
This article, it’s subject and the author are quite bizarre. Johnson begins with a solution and now conducts an experiment by the use of valuable plasma and data time to find a premise. Bateman, a mere historian, attempts to give him some credibility using his vast scientific credentials. What next? will Messers Bateman and Johnson find a skeleton in Petra with an IV line dangling from it’s elbow. The world gets sillier by the day.
The nerve to believe the rest of us want this dude to live forever. What a douche bag.
Until you have completed your first plasma exchange with your son, have you really lived?
While Johnson should have the right to carry out his treatments I see his aims and approach as actively unhealthy and damaging to society and humanity
I’d like to be a fly on the wall the day he looks in the mirror, and sees an old guy looking back at him.
The thing with aging is that we have no reason to see halting it as this impossible scientific feat, like faster-than-light travel or getting a pig to fly. We don’t age because a law of the universe says we must, we age because a handful of biological processes in our bodies get gradually less efficient over time, and evolution didn’t have an incentive to fix the problem. There is also so much about how humans work at a biomolecular level that we could understand given currently available technology, it’s just so mind-bogglingly complex we’ve not had the time to get around to everything.
I doubt Bryan Johnson is himself going to discover anything relevant – a single human is just too small a data point, especially when he’s doing so much at once. But we will get there eventually, humans are never going to stop wanting to live and biomedical science will only get better.
“Immortality consists largely of boredom” – Zefram Cochrane
What a weirdo.
He should be applauded because he is funding longevity research and products which will eventually be available to everyone. It’s analogous to motor vehicles: in 1905 they could only be afforded by tne rich but 8 decades later most people had 1 as production scaled up and cots decreased due to economies of scale. Those rich early adopters spent large amounts of their income funding the early car industry which supported mass benefits later. Another advantage of having a super rich elite.
I have no issues with the “super rich elite” as such, but some of them can be quite creepy.
One cup of green tea, followed by 500 mg of Vitamin C, combine in the body with a potent synergistic impact on organic health:
Synergistic Effects:
Improved Catechin Stability: Catechins in green tea, like EGCG, can degrade in the digestive system. Vitamin C has been shown to stabilize catechins, helping them stay active longer and improving their absorption in the body. This means you might get more health benefits from the green tea when combined with vitamin C.
Enhanced Antioxidant Power: Both vitamin C and the catechins in green tea are powerful antioxidants. Together, they can reduce oxidative stress more effectively than either on its own, which may offer better protection against free radicals that contribute to aging and chronic diseases.
Boosted Immune Function: Green tea has immune-boosting properties, particularly through its anti-inflammatory effects, while vitamin C is well-known for supporting the immune system. Together, they could give your immune health an even bigger boost.
