Biohacker who spends $2,000,000 to ‘live forever’ reveals shocking reason why his 'urine is now blue'

A biohacker who has spent an eye-watering $2 million in his bid to 'live forever' has revealed that a new experiment has left his urine 'blue'.

Bryan Johnson has been on quite a mission to 'conquer death' and 'reverse' the ageing process. To this end, the 47-year-old has been taking part in a lengthy, intense, and costly medical program that he refers to as 'Project Blueprint'.

This project has seen him dabble in some unusual experimental areas - like injecting himself with his son's blood, following a strict diet, exercise regimen, and using UV-free light, red light, and oxygen therapy every day.

And apparently, it's all working out for him, too, as the biohacker claims his stringent habits have helped him achieve the 'heart of a 37-year-old' and the 'lung capacity of an 18-year-old' and even, at least in one area, the biological health of a ten-year-old child.

Now, he has revealed his latest experiment has turned his urine 'blue'.

Announcing the unusual change, Johnson wrote on Twitter: "My urine is now blue."

Why? Well, he says it's because he 'started Methylene Blue' on Tuesday (August 5). According to the National Library of Medicine, Methylene Blue is an FDA-approved medication used to manage and treat methemoglobinemia, which is a condition in which 'hemoglobin decreases its ability to carry oxygen'.

According to the Cleveland Clinic, methemoglobinemia, also known as 'blue baby syndrome', is a 'rare blood disorder that affects how red blood cells deliver oxygen throughout the body'.

Almost all people with the condition have a 'distinctive' shade of blue or purple on their skin, nails or lips.

While it can be inherited, it commonly occurs when patients use specific medications or are exposed to certain chemicals and recreational drugs.

While Johnson hasn't exactly revealed why he's taking the medication, when asked by a follower why he would take a 'synthetic petroleum-based dye', Johnson snapped back: "Was really moved by the Smurfs movie."

Johnson, who starred in his own Netflix documentary, Don't Die: The Man Who Wants to Live Forever, that dropped earlier this year, also appears pretty impressed with the strange side effect, adding that he feels 'like I'm in Avatar'.

The revelation comes as Johnson also revealed he started a new protocol earlier this week called IHHT - another oxygen-propelling system - which he claims can accelerate recovery, improve cognition, raise red blood cells, repair vessels and ultimately slow the speed of ageing.
