Bryan Johnson

Tech entrepreneur; 'Blueprint' / Don't Die longevity project

Bryan Johnson is the tech entrepreneur behind 'Blueprint' and the 'Don't Die' movement, who reportedly spends millions a year measuring and optimizing his biology. He is among the most aggressive adopters in this index: he received follistatin gene therapy abroad (it is not available in the US) and sells a multi-peptide topical serum through Blueprint, documenting results publicly and in granular detail. Inclusion is documentation, not endorsement; several interventions he pursues are experimental and not consumer products.
