The tech millionaire Bryan Johnson once went viral for infusing himself with a litre of his 17-year-old son’s blood plasma. That experiment failed, but it hasn’t distracted him from his life’s mission: reversing ageing. 

Now, the self-declared professional guinea pig has travelled to a libertarian free zone on a remote Caribbean island, to receive experimental gene therapy administered by a company called Minicircle. 

In the crypto city of Próspera, Roatán, the Honduran government grants Minicircle regulatory freedom for medical experiments that are banned by the FDA in the US.
