The Brief An FDA advisory panel recommended this week that six types of peptides be made more available to the public, contradicting advice from FDA scientists. Rachele Pojednic, a Stanford faculty member and chief science officer at Restore Hyper Wellness, said the peptides have not gone through the safety and clinical testing required of approved medications. Pojednic said a growing "gray market" for unregulated peptides raises additional concerns, including unknown contents in vials purchased online. "There's a lot of information on Reddit right now about these peptides, but there isn't a lot of good clinical human subjects data," Pojednic said. Part of the FDA panel's argument for expanding access is that the peptides are already available through a so-called gray market online.
