In an interview with Inc.com’s Jeff Bercovici, Thiel said that the practice — known as parabiosis — is the closest modern science has come to creating an anti-aging panacea.
Thiel — a hedge funder who acted as a delegate for Donald Trump and spoke at the 2016 Republican National Convention — is reportedly obsessed with defying death and extending the human lifespan. He has injected funds into startups that are experimenting with ways to forestall the body’s inevitable decline and death.
“I’m looking into parabiosis stuff,” Thiel told Bercovici, “where they [injected] the young blood into older mice and they found that had a massive rejuvenating effect. … I think there are a lot of these things that have been strangely underexplored.”
Parabiosis experiments began in the 1950s with crude exercises in which rats were cut open and their circulatory systems restructured and manipulated. Recently, some companies have been advancing human trials with parabiosis. Bercovici wrote that U.S. studies in the field are currently lagging behind trials in China and Korea.
A California company called Ambrosia is conducting human trials in which healthy people aged 35 or older receive transfusions of blood plasma from people under 25. Participants pay $8,000 to take part and their health is closely monitored for the two years they receive the transfusions. Participants must live in or have the means to travel to Monterey, CA.
