On April 15, 2026, the FDA moved 12 therapeutic peptides — BPC-157, TB-500, KPV, MOTS-c, DSIP, Semax, Epitalon, GHK-Cu, Melanotan II, LL-37, Dihexa, and PEG-MGF — out of Category 2. On July 23–24, 2026, the Pharmacy Compounding Advisory Committee finalizes their placement on the 503A Bulks List.

PeptidesBeat is an independent editorial desk, not a telehealth brand and not a peptide seller. We do not accept affiliate commissions from compounding pharmacies. We do not accept sponsored content from peptide-adjacent telehealth companies. Our revenue comes from educational products like the Peptide Law Playbook and from a forthcoming paid-newsletter tier. That model keeps our incentives aligned with readers, not advertisers.
We cite primary sources. We distinguish preclinical research from human clinical trials. We don't prescribe, we don't recommend dosing, and we route every clinical question back to licensed practitioners.
