About this episode
Biohackers and longevity clinics claim peptides are a side-effect-free sniper rifle for fat loss and injury recovery, but the reality is often buried in failed clinical trials and regulatory bans. Many popular compounds like BPC-157 have never undergone a single randomized controlled trial in humans, despite their reputation for Wolverine-like healing. This episode dismantles the hype surrounding the gray market, exposing the significant risks of immunogenicity and heavy metal contamination.
