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.This is the story of biohacking… on steroids.
