10 years younger, but…: Man who followed Bryan Johnson’s anti-aging plan spills the downsides

A tech entrepreneur named Max G has stirred conversation after revealing his experience with Bryan Johnson’s Blueprint, a strict regimen designed to slow and even reverse biological ageing.

In a post on X (formerly Twitter), Max shared that after nearly two years on the programme, his biological age had dropped from 28 to 18. According to him, 90% of his biomarkers are now within optimal ranges.

“Almost 2 years on @bryan_johnson's Blueprint: in 2023: always tired, carb-loading, night owl habits. In 2024: turned things around, focused on health & longevity. 2025: 10 YEARS YOUNGER biologically (18 vs 28) with 90% of all biomarkers in optimal ranges,” he wrote.


The claim quickly gained traction, drawing curiosity and scepticism in equal measure.

The Cost of a Longevity Lifestyle

While many were fascinated by Max’s results, one X user asked, “Are there any downsides, though? I’d love to see the full picture.”

Max responded candidly, admitting that the programme had come with trade-offs.

“Downsides I’ve experienced: 1) Social flexibility takes a hit sometimes (especially around late dinners, going out…) 2) Time investment for tracking is real 3) I’ve learned to use the 80/20 rule – perfect adherence isn’t sustainable 4) I go through phases of higher/lower commitment depending on work demands,” he explained.

For those unfamiliar, the 80/20 rule refers to maintaining strict discipline 80% of the time while allowing for flexibility in the remaining 20%.

He also shared key lessons from his journey, stating, “The most important things are nutrition, sleep and exercise, which should be taken care of before thinking about supplements. Tracking progress is important because you can only improve what you measure. Lastly, having supportive friends helps you stay on track and stick to the plan.”

Mixed Reactions from the Public

The post triggered a flood of responses, with some impressed by Max’s discipline and others questioning the practicality of Blueprint.

One user wrote, “It’s amazing what sleep, exercise, and nutrition can do.”

Another was more sceptical, commenting, “Nice to be rich and afford all that.”

Others sought practical guidance. One user asked, “What do I do to start? Not worried about money. Just not sure how to incorporate the powders and pills into a daily routine with food.”

Not all reactions were positive. Some dismissed the concept entirely, with one person writing, “This is so retarded.” Another added, “Easy when you’re young. Let me know when you’re in your 50s. You have to push harder.”

What is Bryan Johnson’s Blueprint?

Blueprint, according to its official website, is described as an “evidence-based” system that includes strict guidelines for diet, exercise, sleep, and supplementation. It also covers skincare and overall well-being.

Johnson, a tech entrepreneur and self-proclaimed longevity experimenter, has spent millions on developing the protocol. His website labels him “the healthiest human on the planet,” attributing this to four years of strict adherence to Blueprint.

The protocol promises benefits such as improved physical strength, enhanced focus and energy, better heart health, and an overall boost in mood.

Is Longevity Science the Future?

While Max G’s transformation has reignited interest in longevity science, debates continue over whether such an extreme routine is feasible for the average person.

Bryan Johnson has been outspoken about his mission, even going as far as to introduce a new ideology, “Don’t Die,” on 7 March. He claims this philosophy is essential for human survival and aims to align artificial intelligence with humanity’s best interests.

For now, Blueprint remains a controversial topic—praised by some as a revolutionary step in health science, dismissed by others as an unattainable luxury.
