Wolverine stack: BPC-157 + TB-500

'Wolverine stack' is the common name for the combination of the peptides BPC-157 and TB-500. Both are studied in repair models, but through very different mechanisms. Here you can read what is in the Wolverine Blend and why researchers study the two peptides together.

What is in the Wolverine Blend?

The Virexa Labs Wolverine Blend contains both peptides lyophilized in one vial:

  • BPC-157: 10 mg – synthetic pentadecapeptide (15 amino acids)
  • TB-500: 10 mg – synthetic peptide derived from thymosin beta-4
  • Total: 20 mg per vial
  • Purity: ≥99% by HPLC

Where does the name come from?

The name refers to the comic-book character Wolverine, known for his healing ability. In the research community, 'Wolverine stack' has become the usual nickname for this combination. It is a nickname, not a scientific term.

Two different peptides

BPC-157 and TB-500 differ greatly in size, origin and mechanism. BPC-157 is a short peptide with a sequence from a gastric-juice protein and is studied in models of angiogenesis and the nitric oxide system, among others. TB-500 is derived from thymosin beta-4 and binds actin, a building block of the cytoskeleton.

Because the two are studied through different routes, researchers combine them in setups where the interplay between both approaches is the focus. More in our BPC-157 vs TB-500 comparison.

Blend or separate?

A blend is convenient if you always use both peptides in a fixed 1:1 ratio. If you want to vary the ratio or study the peptides separately, the individual peptides BPC-157 and TB-500 are the better choice. Both are also sold separately at Virexa Labs.

Storage and quality

Store the lyophilized blend at −20 °C, dry and protected from light. Reconstitute with bacteriostatic water, swirl gently and keep the solution at 2–8 °C. Use our peptide calculator to work out the reconstitution.

Every batch is tested by HPLC for ≥99% purity; the COA is on the product page. Both peptides are on the WADA prohibited list and neither is approved as a medicine. The Wolverine Blend is intended solely for laboratory research and not for human or veterinary use.
