Inside the world of San Francisco 'peptide parties'
A Los Angeles Times investigation details underground gatherings in San Francisco where attendees self-inject unapproved peptides for anti-aging and performance enhancement, including an event held aboard a World War II ship. The reporting coincides with federal policy changes: HHS has issued new compounding restrictions for 503A pharmacies, while the AMA adopted new policies on peptide use. An oncologist writing in MedPage Today and a health law scholar in The Conversation both warn that expanded access under RFK Jr.'s influence lacks safety data.

San Francisco 'peptide parties' draw scrutiny amid regulatory shifts
A Los Angeles Times investigation details underground gatherings in San Francisco where attendees self-inject unapproved peptides for anti-aging and performance enhancement, including an event held aboard a World War II ship. The reporting coincides with federal policy changes: HHS has issued new compounding restrictions for 503A pharmacies, while the AMA adopted new policies on peptide use. An oncologist writing in MedPage Today and a health law scholar in The Conversation both warn that expanded access under RFK Jr.'s influence lacks safety data.
Why it matters
Peptides, short amino-acid chains, occupy a regulatory gray zone between supplements and drugs. Enthusiasts promote them for muscle growth, cognition, and longevity, but most lack FDA approval for those uses. Recent federal moves to loosen access have alarmed clinicians who cite unknown long-term risks, inconsistent dosing, and sterility concerns at compounding pharmacies. The San Francisco scene illustrates how quickly a biohacking subculture can scale when regulatory guardrails shift.
