Peptide blend · BPC-157 + TB-500
Is the Wolverine stack legal?
The short answer
No. The Wolverine stack is not legal to sell or compound for human use anywhere Peptlas tracks.
The Wolverine stack is a seller’s name for a premixed vial of BPC-157 and TB-500. Some reports call BPC-157 alone the “Wolverine peptide”. The name is a market label, not a regulated product, so amounts, ratios and purity vary by seller.
In the U.S., none of its 2 ingredients is on the FDA’s 503A bulks list, so no pharmacy can lawfully compound the Wolverine stack, and selling it for people to inject is selling an unapproved drug, whatever the “research use only” label says. The FDA’s advisory committee recommended BPC-157 and TB-500 for that list in July 2026; the vote is advisory, and the FDA has not acted.
Elsewhere the strictest ingredient decides: the Wolverine stack is restricted in Australia, the UK, the EU, Canada and Brazil, and banned in sport, because WADA prohibits BPC-157 and TB-500.
