# BPC-157 TB-500 References: The Cited Literature and Regulatory Sources

> BPC-157 TB-500 references: the peer-reviewed studies, reviews, and FDA sources cited across this safety brief, with DOIs, PMIDs, and URLs. The full record behind the Wolverine blend digest.

Every quantitative claim across this BPC-157 TB-500 safety brief resolves to an entry below. Peer-reviewed studies and reviews carry DOIs and PubMed links; regulatory facts cite FDA pages.

## How to read this list

This is the full reference list for the BPC-157 TB-500 safety brief. Entries 1 through 10 are the peer-reviewed studies and recent reviews behind the mechanism, efficacy, and safety pages — including the Thymosin Beta-4 tumor/angiogenesis signal (entry 5) and the mdx null functional result (entry 6). Entry 11 anchors the dose-context, half-life, route, WADA, and human-data summaries. Entries 12 through 15 are the FDA regulatory sources behind the legal-status page.

The two constituents carry their own identifiers, logged here for the record: BPC-157 (GEPPPGKPADDAGLV, C62H98N16O22, MW ~1419.5 Da, CAS 137525-51-0, PubChem CID 108101) and TB-500 (Ac-LKKTETQ, C38H68N10O14, MW ~889.0 Da; parent protein Thymosin Beta-4, UniProt P62328). The blend has no identifier of its own — it is a pairing of two specimens, not a single substance.
