BPC-157 and Injury Recovery: What Has Been Studied

What the research covers

BPC-157 has been tested for injury recovery mainly in rodent (rat) studies. No controlled human trial was found. It is a chain of 15 amino acids, part of a larger peptide first found in gastric juice.

In the rodent (rat) studies, researchers cut or crushed a tendon, muscle or ligament. Then they gave the peptide. Most gave 10 micrograms or 10 nanograms per kg, injected into the belly cavity once a day. In a rodent (rat) study of cut Achilles tendons, treated tendons healed better than saline-treated ones. They were stronger, worked better and showed better tissue repair. Rodent (rat) studies of a cut thigh muscle and a cut knee ligament reported similar gains over 72 and 90 days. In the ligament study, the peptide in drinking water or as a cream also helped.

The human record is small. A 2021 review of charts at one Florida clinic looked back at knee joint shots of the peptide. Of 12 people who got only this peptide, 11 had a significant improvement in knee pain. No specific tools measured function. A 2025 pilot gave two adults 10 mg and then 20 mg by IV drip. No side effects were reported.

A PubMed search on 27 September 2026 found no record of it tagged as a clinical trial. No human half-life study was found either. In a rodent (rat) and dog study, the half-life was under 30 minutes.
