BPC-157 + TB-500 for Dogs
The "wolverine stack" is the most searched pet-peptide combo. Here is what the animal data supports, what has never been tested in dogs, and how to think about it honestly.
What's in the Stack
A synthetic pentadecapeptide. In rat models it promoted tendon-cell outgrowth, survival and migration (PMID 21030672) and improved ligament healing (PMID 20225319). Mechanism data is rodent and in-vitro, not canine.
A synthetic fragment of thymosin beta-4, an actin-sequestering protein that supports cell migration and wound repair (PMID 16099219) and dampens inflammation (PMID 30063848). Reviews only; no canine trial.
A 2026 rat Achilles-transection study (PMID 42542926) tested BPC-157 (10 µg/kg/day) and TB-500 (60 µg/kg/day) alone and combined; TB-500 and the combination significantly improved tendon architecture (Movin scores). Rats, not dogs.

Daily Dosing Schedule
Key Takeaways
- BPC-157 and TB-500 are synthetic peptides with soft-tissue-repair activity in rodent and in-vitro models.
- A 2026 rat Achilles study found the combination and TB-500 alone significantly improved tendon architecture (PMID 42542926).
- BPC-157 has been characterized pharmacokinetically in beagle dogs: ~45-51% intramuscular bioavailability, elimination half-life under 30 minutes (PMID 36588717).
- The peptides clear the bloodstream quickly, which is why owner protocols use daily dosing.
- No controlled efficacy trial of BPC-157 or TB-500 in dogs has been published (PubMed searches, 2026: 0 results).
- There is no established or veterinary-endorsed dose for either peptide in dogs.
- The rat tendon doses (µg/kg) are not a canine protocol and should not be scaled to a dog.
- Long-term safety of these peptides in dogs is unstudied.
Frequently Asked Questions
Is there any real study of BPC-157 and TB-500 in dogs?
The only published canine data is a pharmacokinetic study in beagle dogs (PMID 36588717) that measured how BPC-157 is absorbed and cleared. It was not an efficacy or arthritis trial. No controlled study has tested whether either peptide helps a dog heal.
What doses were used in the rat tendon study?
BPC-157 at 10 µg/kg/day and TB-500 at 60 µg/kg/day, given intraperitoneally for four weeks (PMID 42542926). These are rat-model doses in a lab setting, not a recommendation for dogs.
Why do so many sites list confident dog doses?
Because they are copying each other, not a study. No peer-reviewed canine dosing protocol exists. Any specific dog dose you see online is someone’s guess or extrapolation from human or rodent numbers.
What should I actually do?
Talk to a veterinarian, especially one open to discussing regenerative options, and treat online protocols as anecdotes rather than instructions.
