Restriction

FDA places ~19 peptides on Category 2 compounding restriction list

The FDA placed BPC-157, TB-500, Thymosin Alpha-1, AOD-9604, MOTS-c, Selank, Semax, KPV, and approximately a dozen others on its Category 2 list, effectively blocking licensed 503A compounding pharmacies from preparing them for patients.

Reversal announced

HHS announces Category 2 → Category 1 reversal for ~14 peptides

HHS Secretary Robert F. Kennedy Jr. publicly announced that approximately 14 of the previously restricted peptides — including BPC-157, TB-500, Thymosin Alpha-1, AOD-9604, MOTS-c, Selank, Semax, and KPV — would return to Category 1 status pending formal reclassification.

Reversal effective

Category 1 reclassification effective

The reclassification became effective. Licensed 503A compounding pharmacies can again prepare the reclassified peptides for individual patients with a valid, patient-specific prescription. Category 1 status permits compounding while the substance remains under FDA evaluation; it does not constitute FDA approval.
