Biohacker who used son's blood to 'reverse aging' says he's 'transitioning'

Biohacker Bryan Johnson said his body is 'transitioning' as he continues his mission to try and reverse his age.

While the rest of us deal with the various aches, pains and extended hangovers that come with getting older, Johnson has spent the last few years paying millions of dollars to fend off the effects of aging.

With the help of a team of doctors and health experts, Johnson, who is biologically 46, has taken up treatments to achieve the body of an 18-year-old.

Dubbed Project Blueprint, Johnson's experiments to reverse aging include a strict diet, exercise and a meticulous sleep routine, as well as medical procedures ranging from regular blood tests to infusing himself with a litre of his son’s plasma.

What he described as the 'world’s first multigenerational plasma exchange' took place in 2023 and saw Johnson exchange the fluid with both his 17-year-old son and 70-year-old father.

The procedure came in an effort to reduce age-related brain decline, but in July Johnson admitted there were 'no benefits detected' and that he was choosing to 'discontinue' the therapy.

“Young plasma exchange may be beneficial for biologically older populations or certain conditions,” he tweeted at the time. “Does not in my case stack benefit on top of my existing interventions.”

But while that particular experiment proved futile, Johnson has seen results in his efforts to reverse his age.

He took to X this week to share a series of images showing how his appearance had changed throughout his journey, comparing his face now to how he looked in 2018.

The images show a noticeable change. In 2018, Johnson's face was fuller, his hair short and ginger.

Fast-forward six years and a whole range of procedures later, the biohacker's cheekbones are more pronounced, his hair darker and longer.

"Even my Face ID is confused," Johnson wrote alongside the photos, adding: "I'm transitioning..."

In a follow-up post, Johnson asked X users to vote on when he 'peaked' during his journey: 2018, 2023 or 2024.

The results probably didn't turn out quite how Johnson hoped as more than half of voters claimed he peaked in 2018, though 39.3 percent did express belief he looked better now than six years ago.

Johnson didn't seem phased by the claims that he looked better in 2018, however, as he looked ahead to the future with an empty spot in the series of photos to predict what he might look like in 2049.

"Where next," he wrote, prompting one viewer to joke that by 2049 the biohacker would have successfully achieved 'immortality'.
