Biohacker Bryan Johnson has revealed he's 'upgraded' his approach to treatment after giving up on 'injecting [his] son's blood'.
Johnson has made a name for himself thanks to his efforts to avoid ageing at all costs - literally.
The 'biohacker' has spent millions of dollars on research to keep his body younger than his biological age, and has previously spoken about having the heart of a 37-year-old, the skin of a 28-year-old, and the lung capacity of an 18-year-old.

For context, Johnson was born 47 years ago.
As part of his mission, Johnson announced in 2023 that he'd come together with his then-17-year-old son and his 70-year-old father to take part in what he described as 'the world’s first multigenerational plasma exchange'.
The process saw Johnson have a litre of his blood removed and separated the plasma. He then had the same amount of his son's plasma infused into his veins.

Johnson took on the exchange as as a possible treatment for cognitive decline, but on January 28, he shared an update to say he was taking things in a new direction.
The biohacker shared an image of himself holding a large bag of yellow-orange liquid, and wrote: "I am no longer injecting my son's blood."
He announced he'd instead 'upgraded' to 'total plasma exchange'.
Johnson went on to detail the 'steps', saying:

"1. Take out all blood from body
"2. Separate plasma from blood
"3. Replace plasma with 5% albumin & IVIG"
He concluded his post: "Here's my bag of plasma. Who wants it?"

Cleveland Clinic explains that albumin is protein in your blood plasma. If you have a low level of albumin, it could be the result of kidney disease, liver disease, inflammation, or infections, while high levels are often the result of dehydration or severe diarrhea.
IVIG stands for intravenous immunoglobulin, and is a product of the blood which is used to treat conditions by replacing antibodies in the body.
Explaining the reason for his new approach, Johnson claimed in a thread that total plasma exchange has 'great effects in removing toxins, waste products, old misfolded and glycated proteins and immune complexes'.

The biohacker claimed the process has also shown 'measurable effects in delaying and reversing age-related disease including dementia, as well as the capacity to reduce biological age based on various parameters, including blood proteomics and biological aging clocks'.
Johnson is set to put the theory through some 'rigorous' testing, planning: "Bi-weekly protocol, 2x [Total Plasma Exchange] with 5% albumin, spaced by 4 days [and] 20g of IVIG following each TPE session."
He explained: "By implementing this protocol along with thorough measurement, my team and I aim to figure out what works best when it comes to the use of TPE as a rejuvenation and longevity therapy."
Johnson is set to share updates on the process after his upcoming second bi-weekly session.
