Bryan Johnson has issued a scathing response after a doctor compared him to an infamous ‘fraudster’.
Better known online as ‘The Liver Doc’, Dr Cyriac Abby Philips questioned the biohacker about clinical evidence to back up his supplements.
Johnson is well known for his extreme attempts to prolong his life, often promoting his catchphrase, ‘don’t die’.

And while his antics have earned him a huge following on social media, Philips has been more cynical about treatments Johnson sells.
Philips took to social media yesterday (March 30) to claim that Johnson is fraudster who sells ‘potentially dangerous snake oil supplements’, even comparing him to Elizabeth Holmes, who was convicted of fraud through her health tech company.
Philips wrote: “It is terrifying that people do not see Bryan Johnson as actually a well-evolved masculine form of fraudsters Elizabeth Holmes and Belle Gibson, selling both expensive and utterly useless investigations and peddling potentially dangerous snake oil supplements in the name of BLUEPRINT.”

Johnson was quick respond to the claims, firing back that the supplements sold under his Blueprint brand are full of ‘nutrients which have independent and robust scientific evidence’.
Johnson said: “Cyriac why are you so angry? Who hurt you?
“Blueprint offers extra virgin olive oil, proteins, nuts, and nutrients which have independent and robust scientific evidence. They are third party tested. The certificates of analysis are publicly available. They are affordably priced.”

One particular product that Johnson’s company offers is the ‘Blueprint Longevity Mix’, which is purported to promote better sleep, boost energy levels and reduce stress.
On the Blueprint website, it states that this mix has ‘13 health actives’ and high quality ingredients which includes ‘CaAKG, Creatine Monohydrate, Glycine, L-Theanine, reduced Glutathione, Calcium and Magnesium’.
Philips replied to Johnson, saying: “You personally messaged me and I asked some rational questions. Still waiting on your answers.”
He went on to add: “No hate my friend. Just stating facts. I fail to understand how you can sell expensive supplements without any actual clinically relevant evidence to showcase for it?

“For example, how did you come up with these doses? Where are the dose finding studies? Where is the efficacy and safety studies for these multiple supplements featuring multiple botanicals?”
Talking about the longevity mix, Philips continued: “Where is the proof that this mix actually increases life expectancy/ longevity? Is there a preclinical study in mice or primates or pigs? We will get to human studies later. At least proof of concept studies?”
Johnson has not yet responded to Philips’ queries.
