In 2026 the FDA began reversing its 2023 peptide restrictions — but "coming back" is two separate legal tracks, most coverage confuses them, and the official list still hasn't published. This tracker keeps the score, row by row, source by source.

Confidence labels: rows marked "announcement-level" rest on the Feb 2026 HHS announcement and reporting, not a published FDA list. Every row updates the day primary documents drop. Sources per row are in the dataset; key ones: Pharmacy Times · AJMC · Holt Law
Millions of people already buy these compounds in the RUO gray market with Reddit threads as their only guide. We think plain-language legal status, honest risk framing, and named sources beat pretending the market doesn't exist. Our line: we report on this market, we never sell into it — no affiliate links to RUO vendors, ever, per our editorial policy.
Nothing here is medical or legal advice. Compounded peptides are not FDA-approved drugs; RUO compounds are not approved for human use. Coming next in this hub: what "research use only" legally means, how the 503A pathway works, and how to read a certificate of analysis.
