In this Core Memory podcast episode, hosts Ashlee Vance and Kelly Robison interview journalist Jasmine Sun, who recently wrote a New York Times Sunday Business piece on the rapidly growing “Chinese peptide” scene. The conversation walks through what peptides are (mini‑proteins such as GLP‑1, BPC‑157, TB‑500, oxytocin, etc.), the most popular DIY stacks (the “Wolverine” stack of BPC‑157 + TB‑500, GLP‑1s for weight loss, epitalon for sleep, “Redda” for appetite), and how the phrase “Chinese peptides” has become a viral meme at parties and on TikTok. Sun describes the underground ecosystem: gray‑market websites that sell research‑grade peptides manufactured in China, DIY mixing in basements, free‑testing labs in San Francisco, and the peptide rave held in Frontier Tower that combined demos with a techno party. Safety concerns dominate the discussion – lack of FDA‑approved status, possible contamination, cancer‑risk pathways, and anecdotal adverse events (hair loss, nausea). The hosts explore regulatory ambiguity, noting that the Biden administration has softened enforcement against mis‑labelled research chemicals, while the FDA is reviewing compounding bans. They also touch on broader geopolitical angles (China’s dominance in active‑pharmaceutical‑ingredient production) and cultural drivers: a bio‑hacking mindset that prizes self‑directed health, distrust of the medical establishment, and the appeal of cheap, fast‑acting GLP‑1 analogues. The episode ends with Sun’s personal background (Stanford sociology, product‑manager stints, Substack journalism) and a meta‑discussion about the challenges of covering niche biotech topics in legacy media versus independent platforms.
