BPC-157 is the peptide dog owners ask about most. This guide pulls together everything we have published on it.
What is BPC-157?
A synthetic peptide of fifteen amino acids, derived from a protein found in gastric juice. It is made in a laboratory and usually sold as a freeze-dried powder in a vial, or mixed into drops, capsules and treats.
Why are dog owners interested?
Mostly because of animal studies on tendon, gut and skin injury, and a lot of owner stories online. Common reasons people look it up include stiff older dogs, recovery after injury and long-running skin or gut problems.
Does it work in dogs?
Nobody knows. The research is mostly in rats and mice. We are not aware of any large controlled trial in dogs. Read what the research actually shows.
Is there a dose for dogs?
No established one. Charts you see online come from sellers, not from canine trials. More in BPC-157 dosage for dogs.
Is it safe?
Short rodent studies have not reported serious harm, but long-term and dog-specific safety data do not exist. See side effects and risks.
Is it legal in the UK?
It is not an authorised veterinary medicine. It is sold as a research compound. See Are dog peptides legal in the UK?
Which brands sell it?
We compare eight on UK shipping, pricing, refunds and certificates in our brand rankings. Only one ships from within the UK.
How does it compare with TB-500?
They are different compounds, often sold together. See BPC-157 vs TB-500.
The sensible first step
Talk to your vet. Ask what authorised options exist, and what they make of the evidence.
