BPC-157 is a lab-made chain of 15 amino acids, copied from part of a protein in human stomach juice. Scientists have tested it in animals for healing of tendons, muscle and the gut. Very little has been tested in people.
Why scientists study it
- In lab studies it helped new blood vessels grow in two ways: through VEGFR2, and through a second route that raises nitric oxide.
- In animals it improved healing of tendon, ligament, muscle and bone, and raised growth hormone receptor in tendon cells.
- It protected the stomach and gut from damage caused by alcohol, NSAID painkillers and stress.
Three studies to know
2017 · J Mol Med
Hsieh and colleagues showed that BPC-157 switches on VEGFR2 and raises its levels. This is a specific pathway behind its effect on blood vessel growth. Read the paper
2003 · J Orthop Res
Staresinic and colleagues reported faster healing of a cut Achilles tendon in rats, with a stronger tendon and more tendon cells. Read the paper
2025 · HSS Journal
Vasireddi and colleagues reviewed BPC-157 in sports medicine. They found benefits in animals that are still mostly unproven in human trials. Read the paper
Safety and legal status
- Animals tolerated it well, with no organ damage, gene damage or cancer found. Human safety data are very thin: fewer than 30 people appear in published studies.
- It is not approved by the FDA, the EMA or the MHRA. The World Anti-Doping Agency bans it at all times (class S0).
- For laboratory research use only. It is not approved for human use.
