Biohacker Who Spends $2,000,000 To 'Live Forever' Explains Bizarre Reason His Urine Turned Blue

A well-known biohacker who has poured an unbelievable $2 million into his quest to 'live forever' has just shared something unexpected — his urine has turned blue.

Bryan Johnson has made headlines for his mission to slow down aging and fight off death itself. At 47 years old, he’s been committed to what he calls 'Project Blueprint', a high-cost and highly detailed anti-aging program that’s taken over nearly every part of his life.

As part of this lifestyle overhaul, Johnson has explored a wide range of experimental routines. These include receiving blood transfusions from his own son, sticking to an ultra-strict diet and exercise routine, and using therapies like red light, oxygen sessions, and light that mimics the sun without the UV damage — all on a daily basis.

And surprisingly, Johnson says all of it is working for him. He claims to now have the 'heart of a 37-year-old', the lung function of someone aged 18, and even believe it or not — the biological health of a 10-year-old in at least one part of his body.

His latest update? He shared that his new experiment has caused his urine to turn bright blue.

He made the announcement on Twitter, simply writing: "My urine is now blue."

So why the sudden change in color? Johnson says it’s because he started taking something called Methylene Blue on Tuesday, August 5. According to the National Library of Medicine, this is an FDA-approved drug used to treat a condition called methemoglobinemia. In this condition, hemoglobin becomes less effective at transporting oxygen through the blood.

The Cleveland Clinic also explains that methemoglobinemia — sometimes called 'blue baby syndrome' is a rare blood disorder that affects how oxygen moves through the body. It impacts how red blood cells deliver oxygen, which can cause serious issues if untreated.

People who have this condition often show a blue or purplish color on their skin, lips, or fingernails. The discoloration is usually quite noticeable.

While some people inherit it genetically, others develop it after being exposed to certain medicines, chemical compounds, or even recreational drugs.

Even though Johnson hasn’t gone into detail about why he’s using Methylene Blue, he did respond sharply when someone on social media asked why he’d take a 'synthetic petroleum-based dye'. His reply was: "Was really moved by the Smurfs movie."

Johnson, who’s featured in the Netflix documentary Don't Die: The Man Who Wants to Live Forever, which came out earlier this year, seems to be pretty amused by the side effect. He even added that it makes him feel “like I’m in Avatar.”

This surprising revelation came right after he announced yet another part of his longevity routine: a new protocol called IHHT. It's another oxygen-based therapy that he says boosts recovery, enhances brain function, increases red blood cells, supports blood vessel repair, and slows down aging even more.
