The Wolverine blend is a research preparation that combines two peptides, BPC-157 and TB-500, in a single vial. Both peptides have been studied separately in preclinical models of tissue repair, and they are often discussed together because they appear to act through different mechanisms. PRIME supplies the Wolverine blend strictly for laboratory research use; the exact amount of each peptide per vial is stated on the product page and on the batch COA.
What is the Wolverine BPC-157 and TB-500 blend?
A peptide blend is simply two or more peptides lyophilized together in a defined ratio. In this case the components are:
- BPC-157: a synthetic pentadecapeptide (15 amino acids) with the sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. It is a partial sequence of a larger protein described in gastric juice, and the name stands for Body Protection Compound.
- TB-500: a synthetic peptide related to thymosin beta-4, a naturally occurring 43-amino-acid protein involved in actin regulation. TB-500 is generally described as being based on the actin-binding region of thymosin beta-4. The specific sequence supplied is confirmed on the COA.
Neither BPC-157 nor TB-500 is an approved medicine in the United States. Both are research compounds, and the blend is a research convenience rather than a product with any approved use.
How BPC-157 and TB-500 work: mechanisms studied in research
BPC-157
BPC-157 has been studied mainly in rodent models. Research has linked it to angiogenesis, the formation of new blood vessels, including effects on VEGF receptor 2 signaling. It has also been studied for interactions with the nitric oxide system, for effects on fibroblast migration and on the FAK-paxillin pathway involved in cell adhesion, and for increased growth hormone receptor expression in cultured tendon fibroblasts. It is notable for being stable in gastric juice in experimental settings, which is unusual for a peptide.
TB-500
Thymosin beta-4, the parent protein of TB-500, is a major G-actin-sequestering molecule. By binding actin monomers, it helps regulate the assembly of the actin cytoskeleton, which is central to cell shape and cell migration. Research on thymosin beta-4 and its fragments has examined cell migration, angiogenesis, wound closure in animal models and anti-inflammatory signaling, as well as cardiac tissue research in rodents.
Why researchers study them together
The interest in combining the two comes from their different profiles: BPC-157 is most associated in the literature with vascular and growth-factor signaling, while TB-500 is associated with actin dynamics and cell motility. A blend lets a lab work with both in one preparation. The trade-off is attribution. When two peptides are given together, any observed effect cannot be assigned to one or the other without single-compound control groups. Studies that need to separate the contributions usually run BPC-157 alone, TB-500 alone and the combination side by side.
Areas of research
- Tendon and ligament models: BPC-157 has been studied in rodent models of tendon and ligament injury.
- Muscle injury models: both peptides have been investigated in animal studies of muscle damage and repair.
- Wound healing and angiogenesis: thymosin beta-4 and BPC-157 have each been studied for effects on blood vessel formation and wound closure in animals.
- Gastrointestinal research: BPC-157 has been studied in rodent models of gastrointestinal lesions.
- Combination study design: the blend itself is of interest for research on whether complementary mechanisms produce additive effects in preclinical models.
This research is preclinical. Results in animal models do not establish safety or effects in people.

Handling and storage in the lab
The blend is shipped as a lyophilized powder. Store unopened vials refrigerated, or frozen for longer periods, sealed and protected from light and moisture. Allow a cold vial to reach room temperature before opening to limit condensation.
For laboratory work, the blend is commonly reconstituted with bacteriostatic water. Add the diluent slowly down the inside wall of the vial and swirl gently until the powder dissolves; do not shake. Because the vial contains two peptides, record the amount of each component from the product page or COA when you calculate solution concentrations, and label the vial with both. Keep the reconstituted solution refrigerated and protected from light, and avoid repeated freeze-thaw cycles.
Use gloves and eye protection and follow your institution's rules for handling and disposing of research materials.
Quality and lab results
A blend adds a quality question that single peptides do not have: both components need to be confirmed. Every batch of the Wolverine blend sold by PRIME is tested by an independent laboratory, and the certificate of analysis for each lot is published on the lab results page. Review the COA for your lot to confirm the identity and content of both peptides before starting work.
Current vial contents and batch details are listed on the Wolverine BPC-157 + TB-500 product page.

Wolverine blend FAQ
What is in the Wolverine peptide blend?
The Wolverine blend contains BPC-157 and TB-500 lyophilized together in one vial. The amount of each peptide is stated on the product page and confirmed on the certificate of analysis for each batch.
Why combine BPC-157 and TB-500 in research?
The two peptides have been studied for different mechanisms: BPC-157 mainly for angiogenesis and growth-factor signaling, and TB-500 mainly for actin regulation and cell migration. Researchers combine them to study whether these mechanisms interact in preclinical models.
Is a blend better than buying BPC-157 and TB-500 separately?
It depends on the research question. A blend is convenient when a study is designed around the combination. When a study needs to attribute an effect to one peptide, separate compounds and single-compound control groups are the better design.
Are BPC-157 and TB-500 approved drugs?
No. Neither BPC-157 nor TB-500 is an approved medicine in the United States. Both are research compounds, and the blend is supplied for laboratory research use only.
How should the blend be stored?
Keep lyophilized vials refrigerated or frozen, sealed and away from light. After reconstitution with bacteriostatic water for lab use, keep the solution refrigerated and protected from light and avoid repeated freeze-thaw cycles.
For laboratory research use only. Not for human consumption. Not a drug, food or cosmetic.
