How Peptides Conquered the Internet
Ezra Marcus, reporter on internet subcultures, and Jasmine Sun, writer on AI and Silicon Valley culture, unpack how peptides migrated from bodybuilding forums to Bay Area biohackers and teen influencer circles. They trace China’s role as supplier, the Silicon Valley risk-taking that normalized injections, and the influencer pathways that brought peptides into mainstream youth culture.
