Research material and lot documents
Wolverine peptide is a market nickname, not a scientific name, and it usually refers to the pairing of BPC-157 and TB-500 that sellers call the Wolverine stack. Some sources use the name for BPC-157 alone. The Curo recovery catalog listing for BPC-157 + TB-500, 5 mg + 5 mg shows how one seller states the contents of the pair.
Healthline describes the Wolverine stack as a combination of two synthetic peptides, BPC-157 and TB-500, and says the name references a Marvel character's regenerative healing powers.

FDA's July 2026 briefing document quotes a clinic website that says BPC-157 "has been called 'wolverine compound' by many." Source: FDA briefing document on BPC-157, July 23-24, 2026. The same name therefore appears for the single peptide and for the pair.
FDA's bulk drug substances page lists the components under their own names, BPC-157 and "Thymosin beta-4, fragment (LKKTETQ), also known as TB-500." Source: FDA bulk drug substances page, content current as of April 22, 2026.
The stack has two components, BPC-157 and TB-500. The listing linked above states 5 mg of BPC-157 and 5 mg of TB-500, packaged separately and not pre-mixed. The two masses add to 10 mg by arithmetic. They describe two different peptides, so 10 mg is not an amount of either one. These are label contents, and a lot report records the measured material separately.
The name does not fix a formula or a format. FDA's July 2026 briefing document describes websites that sell BPC-157 and TB-500 together as one multiple-ingredient product, some labeled for research purposes only. Source: FDA briefing document on BPC-157, July 23-24, 2026.
PubChem lists BPC-157 as a 15-residue peptide, Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val, with formula C62H98N16O22 and a molecular weight of 1419.5 g/mol. Source: PubChem BPC-157 record, CID 9941957. A 2011 rat tendon-cell paper describes BPC 157 as a partial sequence of body protection compound, which its authors say was discovered in and isolated from human gastric juice. Source: 2011 BPC-157 rat tendon-cell study, PMID 21030672. The BPC-157 site covers this peptide on its own.
FDA's TB-500 record lists the name "N-terminal acetylated 17-23 fragment of thymosin beta 4" and the sequence N-acetyl-Leu-Lys-Lys-Thr-Glu-Thr-Gln, seven residues. PubChem gives the formula C38H68N10O14 and a molecular weight of 889.0 g/mol. Sources: FDA TB-500 fragment identity record and PubChem acetylated fragment reference, CID 62707662. Full-length thymosin beta-4 is a separate 43-residue protein with its own FDA record. Sources: FDA thymosin beta-4 identity record and UniProt thymosin beta-4 entry P62328. The TB-500 site covers the fragment in detail. Listing: TB-500 5 mg listing at Curo.
A pair of separate peptides has two sets of identifiers. The TB-500 vs BPC-157 comparison sets them side by side.

One controlled animal experiment placed BPC-157 and TB-500 in the same model, a 2026 rat Achilles tendon study with a combination group. The authors reported no additional benefit from the combination compared with either peptide alone. Source: 2026 BPC-157 and TB-500 rat study, PMID 42542926.
A 2021 chart review from one clinic included four people who received BPC-157 with thymosin beta-4. Its abstract describes no comparison group. Source: 2021 knee-pain chart review, PMID 34324435. ClinicalTrials.gov returned no record for BPC-157 and TB-500 together on October 15, 2026. Source: dated ClinicalTrials.gov search for BPC-157 and TB-500. The BPC-157 and TB-500 together page gives the details and limits.
KLOW and GLOW are other market names for blends that also contain BPC-157 and TB-500, with more components added. The KLOW vs GLOW vs Wolverine comparison lists the stated components and amounts of all three.
The TB-500 vs BPC-157 comparison covers sequence, source, formula and study models for each peptide. The Wolverine peptide for sale page explains what to check on a listing. Curo's lot certificate library publishes lot reports for the vials.
