“Wolverine Stack” is not a scientific name: it is the nickname given to the mixture of two peptides studied for tissue repair, BPC-157 and TB-500. This guide explains what these two molecules are, what research has actually shown, and what distinguishes Wolverine from KLOW.

The BPC-157
BPC stands forBody Protection CompoundThis 15-amino-acid peptide (Gly-Glu-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val) is based on a portion of a protein found in gastric juice. It is remarkably stable, even in acidic environments. Most of the publications come from Predrag Sikirić's team in Zagreb and focus on rodents: healing of tendons, ligaments, and muscles; protection of the digestive mucosa; and formation of new blood vessels. Data in humans are virtually nonexistent.
The TB-500
La thymosin β4TB-500 is a natural protein of 43 amino acids that regulates actin, the structural framework of cells, and plays a role in cell movement. "TB-500" generally refers to a synthetic fragment of its active region (the 17-23 sequence, Leu-Lys-Lys-Thr-Glu-Thr-Gln), the region that binds actin. Research focuses on wound healing and cell mobilization towards injury, again primarily in animals.
The idea of the mixture: two different mechanisms, one on the vessels and tissue repair, the other on the arrival of cells, studied together.

| QuestionAre they authorized medications? | Response by 01/11/2026No, neither the BPC-157 nor the TB-500, in France or in the European Union. |
| QuestionAre they banned in sports? | Response by 01/11/2026Yes: BPC-157 and thymosin β4 and its fragments are on the World Anti-Doping Agency's list of prohibited substances. |
| QuestionIn what form is the Wolverine sold? | Response by 01/11/2026In lyophilized powder form, as a research reagent, without medical use. |
Wolverine or KLOW?

Frequently Asked Questions
What is the Wolverine Stack?
The nickname for a mixture of two research peptides in equal parts: BPC-157 and TB-500. At PeptiLine, the 10 mg vial contains 5 mg of each.
What are the BPC-157 and the TB-500?
BPC-157 is a 15-amino-acid peptide derived from a gastric juice protein; TB-500 is a synthetic fragment of thymosin β4, a protein that regulates actin. Both are being studied for tissue repair.
Have BPC-157 and TB-500 been tested in humans?
Almost none. The vast majority of studies are on rodents; human data are virtually nonexistent. Neither is authorized as a medicine.
Is the Wolverine Stack banned in sports?
Yes. BPC-157 and thymosin β4 and its fragments, including TB-500, are on the World Anti-Doping Agency's list of prohibited substances.
What is the difference between Wolverine and KLOW?
Wolverine (€49.90) contains BPC-157 and TB-500. KLOW 80 mg (€89.90) adds 50 mg of GHK-Cu and KPV.
