Wolverine
Not approvedBanned in sport
Wolverine is BPC-157 and TB-500 used together. One rat study tested the pair and found no added benefit over either peptide alone. The rest of the research is on each peptide by itself, and almost all of it was in animals or lab cells.
Also known as Wolverine blend, Wolverine stack

Overview
Key points
- Wolverine is a mix of 2 peptides: BPC-157 and TB-500.
- One rat study gave BPC-157 and TB-500 together after a tendon injury. The pair worked no better than either peptide on its own.
- No study has tested Wolverine in people.
- Most of the research behind Wolverine is on BPC-157, and most of those studies used animals. TB-500 has no published results from people yet.
- Wolverine is not an approved medicine. It is banned in sport, because both of its peptides are banned.
- A draft US policy from October 2026 covers BPC-157 and TB-500 one at a time. Under it, HHS does not plan to act against licensed pharmacies that make them for a patient with a prescription. It does not cover blends like Wolverine.

How much research each peptide has
BPC-157 has far more research than TB-500. Both bars use the same scale, so you can compare them.
What the 2 peptides were studied for
Both peptides were studied for wound healing, for muscles and tendons, and for the brain and nerves. Almost all of these results come from animals and lab cells.

| Skin, hair and wounds | 130 | 8 |
| Stomach and gut | 128 | – |
| Brain and nerves | 95 | 8 |

Status and safety
Is Wolverine approved?
No. Wolverine is not an approved medicine, and neither BPC-157 nor TB-500 is an approved drug in the US.
HHS published a draft policy on October 30, 2026. Under it, HHS does not plan to act against licensed pharmacies or physicians that make BPC-157 or TB-500. Each product must be for a patient with a prescription, and strict conditions apply. The policy covers one peptide per product, so it does not cover blends like Wolverine. It is a draft and gives no legal rights. Public comments are open until November 13, 2026.4
Is Wolverine safe?
No study has checked whether Wolverine is safe.
There is little safety data on the 2 peptides. BPC-157 has 24 safety results, including 8 from people. TB-500 has 1. Most come from lab cells and animals.
Quality also changes from product to product. A 2026 preprint looked at 6,441 lab tests of research peptides sold online, including BPC-157 and TB-500. Purity and the amount of peptide in each vial varied widely2.
Questions and more
Common questions
What is the Wolverine peptide?
Wolverine is a name for BPC-157 and TB-500 used together. It is not an approved medicine.
Has Wolverine been tested in people?
No. One rat study gave BPC-157 and TB-500 together after a tendon injury, and the pair worked no better than either peptide alone. No study has tested the pair in people.
What do BPC-157 and TB-500 do?
In studies, both were tested for wound healing, for muscles and tendons, and for the brain and nerves. Almost all of that research was in animals and lab cells.
Is Wolverine banned in sport?
Yes. WADA bans BPC-157 and TB-500 by name, so the blend is banned too.
Can a US pharmacy make Wolverine?
The HHS draft policy from October 2026 does not cover Wolverine. It covers only one peptide per product, made for a patient with a prescription.
