What is the Wolverine stack?
The Wolverine stack is a nickname for using two research peptides together: BPC-157 and TB-500. It is named after the comic book character known for healing fast.
People use either two separate vials or one vial with both peptides already mixed. It is not a medicine and not a product with a fixed recipe.
What is the Wolverine stack used for?
It is promoted for recovery from injuries, especially tendons, ligaments and muscles. The idea is that BPC-157 helps repair at the injury site, while TB-500 helps cells move to the area and calms inflammation.
That reasoning comes from animal and lab studies of each peptide on its own.
What does the research show?
The Wolverine stack has never been tested as a combination, in people or animals. The evidence for each part is limited:
- BPC-157: mostly animal studies, plus three small human pilot studies of 2 to 16 people. A 2025 review said it shouldn’t be recommended for clinical use until proper trials are done.
- TB-500: no published human trials; most research is on the larger natural protein it comes from.
Wolverine stack side effects and risks
The side effects are unknown, because neither peptide has been properly tested in people. Researchers have raised possible concerns about effects on blood vessel growth, and products sold online are not checked for purity, strength or contamination.
Is the Wolverine stack legal?
Neither BPC-157 nor TB-500 is approved for human use by the FDA or any other regulator. In 2026 the FDA moved both off its list of compounding substances with safety concerns and an advisory committee recommended allowing them in compounding, but neither step is an approval.
Both are banned at all times by the World Anti-Doping Agency, so tested athletes can’t use them.
How do you mix the Wolverine stack?
Each peptide, or a blended vial, is mixed with bacteriostatic water. The BPC-157 and TB-500 pages each have a calculator for syringe units, and the reconstitution guide explains the steps.
