Pre-mixed blend (1:1)
A pre-mixed research blend combining BPC-157 and TB-500, studied together for complementary tissue-repair and recovery pathways. The vial is labelled Wolverine, which is the name this combination is commonly known by — the page is titled by its two ingredients so you can see exactly what is in it.
Mechanism#
Combines a gut-derived repair peptide (BPC-157) with the cell-migration regulator TB-500. Research pairs them to study complementary angiogenesis and tissue-recovery pathways.
Areas of research#
- Combined tissue-repair models
- Tendon, ligament and muscle research
- Angiogenesis and cell migration
- Recovery-pathway studies

Check your certificate#
- BPC-157: 1419.55 (monoisotopic 1418.70), seen as ions near 1419.7 and 710.4. It is a free acid, C62H98N16O22.
- TB-500: 4963.44 for full-length thymosin β4 (monoisotopic 4960.49). A mass near 889 is the seven-residue fragment sold under the same name, a different substance.
- Each component on its own line. A blend certificate should identify and quantify every component separately, and the two measured amounts should sit close to the 1:1 ratio on the label.
- Quantity is not identity. Our blend certificates report how much of each component is present, not its mass. The identity of the TB-500 rests on the manufacturer’s certificate for the source material, and we have asked the laboratory to confirm what it was measured against.
- Purity, if reported, with the method named and given for each component rather than as one overall figure.
Ask about the documentation for the batch we would ship before you order. How to check a certificate yourself: verifying a COA.
What’s in the vial#
| Fill | 10mg, 20mg or 30mg per vial, BPC-157 and TB-500 in a 1:1 ratio |
|---|---|
| Components | BPC-157 and TB-500 (full-length thymosin β4). The vial is labelled Wolverine, the name this combination is commonly known by. |
| Purity and content | Purity is the share of what was detected that is each named peptide. Net peptide content, how much of the powder’s weight is peptide rather than salt and water, is a separate number. How much is in the vial. |
Handling at a glance#
| Solvent | Bacteriostatic or sterile water |
|---|---|
| Sealed vial | 2–8°C, dry and dark. Let it reach room temperature before opening. |
| Once in solution | 2–8°C. Avoid thawing and refreezing the same volume. |
| Worth knowing | The TB-500 is a 43-residue protein with structure to lose, so foaming is denaturation rather than a cosmetic problem. Swirl rather than shake. |

What the research covers#
The guide linked here covers how a blend should be checked, not a study of the combination. For the components: published work on BPC-157 is overwhelmingly in rodents, much of it from one research group, and a 2026 systematic review of the human evidence found three small uncontrolled studies with 30 participants in total. The thymosin β4 literature is overwhelmingly preclinical. Neither is a licensed medicine in the UK. Read the full guide, with sources: How Peptide Blend Research Kits Should Be Checked.

Questions#
What is in the vial?
BPC-157 and TB-500 (full-length thymosin β4) in a 1:1 ratio, in one vial. The vial is labelled Wolverine, the name the combination is commonly known by.
What molecular weight should the certificate show?
Two figures, one for each component: 1419.55 for BPC-157 (ions near 1419.7 and 710.4) and 4963.44 for TB-500 as full-length thymosin β4. A mass near 889 would be the TB-500 fragment, a different substance.
How should it be stored?
Sealed vial at 2-8°C, dry and dark. Once reconstituted with bacteriostatic or sterile water, keep it at 2-8°C and avoid thawing and refreezing the same volume.
Is there a batch certificate?
Yes. The certificate for the current batch is available on request: email orders@pioneerpeptides.co.uk with the product and size.
Is it for human use?
No. It is supplied for laboratory research only, and we do not give guidance on human or animal use.
A batch-specific Certificate of Analysis is available on request. New to handling lyophilised material? See our reconstitution guide, storage guide and how to read a COA.
