Peptides decoded: what they are, safety risks, and regulatory shifts
Peptides are short amino‑acid chains; some have FDA‑approved uses (e.g., GLP‑1 diabetes/weight‑loss drugs), but many non‑FDA peptides sold online lack solid human safety data and dosing guidance. Most evidence comes from animal studies, with long‑term risks unknown. In 2023 the FDA tightened compounding rules, creating a gray market for peptides online. While some officials push for broader access, doctors warn that careful physician oversight is essential until more robust human data on safety and dosing emerge.
