Wolverine stack peptides are two injectable products, BPC-157 and TB-500, promoted online under that nickname for faster healing. Here is what they are, what is actually known about them, and where Canadian law stands.
Short answer: neither BPC-157 nor TB-500 is an authorized drug in Canada. Health Canada has warned Canadians not to inject peptides obtained online and has seized them from sellers. We do not supply the Wolverine stack.
What are the Wolverine stack peptides?
| Peptide | What it is | Where the evidence comes from | Status in Canada |
|---|---|---|---|
| BPC-157 | A synthetic chain of 15 amino acids, based on a fragment of a protein found in stomach juice | Mostly rat and cell studies, largely from one research group. Human trials are very limited. | Not authorized |
| TB-500 | A synthetic peptide related to thymosin beta-4, a protein involved in cell movement and repair | Animal studies. It became known through horse racing, where it is banned. | Not authorized |
The name borrows from the comic-book character who heals instantly. The marketing promises the same for tendons, ligaments, muscles and joints.
What does the evidence really show?
- Animal results are not human results. Many compounds that help a rat tendon heal fail when tested properly in people. The human trials that would settle the question have not been done.
- Long-term safety is unknown. Both peptides act on blood-vessel growth and cell migration. What that means over months or years in people has not been studied.
- The product itself is unverified. No regulator checks what is in a vial labelled as a research chemical. Health Canada has reported contamination in seized injectable peptides.
- No authorized dose exists. Dosing charts online are written by sellers and forum users.
Is the Wolverine stack legal in Canada?
No. BPC-157 and TB-500 have not been authorized by Health Canada, so they have no Drug Identification Number and cannot legally be sold for human use. A label reading “research use only” or “not for human consumption” does not change that when the product is sold to the public with dosing advice. Health Canada has issued public advisories naming BPC-157, executed warrants against online sellers and seized thousands of vials.
Pharmacies cannot dispense them and prescribers cannot write a valid prescription for a product that is not an authorized drug. A clinic offering them is working outside the system that protects patients.
Athletes: both are banned
BPC-157 has been on the World Anti-Doping Agency Prohibited List since 2022, and thymosin beta-4 and its derivatives, including TB-500, are prohibited as growth factors. They are banned at all times. The Canadian Centre for Ethics in Sport enforces the list in Canada.
What helps an injury heal
- A diagnosis. A tendon tear, a tendinopathy and a stress fracture need different care. See a physician, sport-medicine clinic or physiotherapist.
- Progressive loading. Supervised, graded exercise has the strongest evidence for most tendon and muscle injuries.
- Sleep, protein and time. Unexciting, and effective.
- Authorized pain relief when you need it. A pharmacist can tell you which non-prescription option suits you and your other medications.

What is the Wolverine stack?
An informal name for the combination of two unauthorized injectable peptides, BPC-157 and TB-500, promoted online for injury recovery.
Is BPC-157 legal in Canada?
BPC-157 is not an authorized drug in Canada. It cannot legally be sold for human use, and Health Canada has named it in a public advisory.
Is TB-500 legal in Canada?
No. TB-500 is not authorized by Health Canada and has no approved human use.
Can a Canadian pharmacy or doctor provide the Wolverine stack?
No. A licensed pharmacy can only dispense authorized drugs, and neither peptide is one.
Does the Wolverine stack work?
That has not been shown in people. The evidence is almost entirely from animal studies.
I already injected a peptide from an online seller. What should I do?
Stop using it and speak to a pharmacist or physician, especially if you have redness, swelling or pain at the injection site, fever, or feel unwell. You can also report a side effect to Health Canada.
