Legal & Regulatory

Are BPC-157 and TB-500 still legal after the April 2026 reclassification?

Updated 2026-05-02

The regulatory picture changed in April 2026. On April 15, 2026, US regulators announced that 12 peptides - including BPC-157, TB-500, Semax, Epitalon, Melanotan II, and injectable GHK-Cu - would be removed from the Category 2 list that had previously restricted them. That change took effect April 23, 2026. Big caveat: removed from Category 2 is NOT the same as approved. The formal review for whether 503A pharmacies can legally compound these is scheduled for July 23-24, 2026. Until that review concludes, the access path is: licensed physician writes a prescription, licensed 503A compounding pharmacy fills it.

IfIf you were using BPC-157 or TB-500 from a licensed 503A pharmacy before the 2023 restriction
Thenthen talk to your prescriber and pharmacy after the July 2026 PCAC review to confirm the current pathway
IfIf you're buying from a gray-market source and relying on the April 2026 announcement as legal cover
Thenthen it doesn't work that way - research chemical vendors are still outside the framework
IfIf you need a formal prescription pathway
Thenthen work with a physician and a PCAB-accredited compounding pharmacy after July 2026
