A biohacker who spends $2 million a year trying to reverse ageing has left people stunned after sharing photos of what he looked like before he started his anti-ageing project.
Bryan Johnson, 46, recently posted photos of himself to show the physical transformation he has undergone since beginning Project Blueprint.
The biohacker first announced his extreme anti-ageing attempt in 2021 and has continued to document his progress on social media, with him going as far to say he has 'no plans to die'.

But naturally, many people have questions about what exactly Bryan is undergoing.
What is a biohacker?
A biohacker is somebody who self-experiments with techniques and collects data on the human body in a bid to determine what works best for them.
In Bryan's case, he is self-experimenting with extreme anti-aging and longevity methods in an attempt to reverse his biological age.
What does his ‘rigorous’ routine involve?
Bryan's intense routine includes a set calorie goal, intermittent fasting, daily supplements and medications, a strict sleep schedule, red light therapy and more.

He has a team of 30 doctors headed by Cambridge-based anti-ageing expert Dr Oliver Zolman, who closely monitor his blood, heart, liver, kidneys, brain, blood vessels and sexual health.
Bryan is vegan and consumes exactly 1,977 calories per day, with his meals mainly made up of whole foods.
Everyday he wakes up at 4.30am, exercises for one hour, sleeps in a completely empty room and takes dozens of supplements.
The benefits
Bryan claims that Project Blueprint has led to him having the lung capacity and fitness levels of an 18-year-old, with the heart of a 37-year-old and the skin of a 28-year-old.

He once told the BBC: "My left ear is 64, my fitness tests say I'm 18, my heart is 37, my diaphragm strength is 18," admitting that some body parts are older than others.
Of course, there are more simple anti-ageing methods - such as eating well and regularly exercising - which won't set you back by millions of pounds.
So, even though Bryan's internal body clock is now younger, what about his external one?
The American entrepreneur has joked this week that his smartphone's Face ID feature fails to recognise him now as he has physically changed so much.

"Even my Face ID is confused. I'm transitioning...," Bryan wrote on X yesterday along with three photos of himself - one from 2018, another from 2023 and a final from this year.
Bryan's physical appearance has very obviously changed since 2018, with his face looking slimmer and complexion looking much clearer.
Does it really work, though?
While Bryan claims his experiment is working and his reducing his biological age, the entrepreneur's project has been met with criticism from experts.

Longevity scientist Andrew Steele previously stated that genetics play the largest role in determining a person's life expectancy, and genetics cannot be changed.
Meanwhile, Moshe Szyf, a professor of pharmacology and therapeutics, has shared his doubts about science being capable of achieving the results Bryan has claimed he's achieved.
