BPC-157 vs KPV
Tissue repair vs anti-inflammatory — two complementary gut peptides
BPC-157
A 15-amino-acid stretch lifted from a protein in human gastric juice. Best-known use is soft-tissue repair, with a quieter second life as a gut-healing protocol.
Best for
Best when you need to rebuild tissue — broad soft-tissue and gut-lining repair with an angiogenic mechanism.
Read full pageKPV
The three-amino-acid tail of α-MSH. Anti-inflammatory in test tubes and animals; some small IBD signal in humans.
Best for
Best when the problem is inflammation itself; KPV is an α-MSH fragment used for gut inflammation of the IBD type.

BPC-157 repairs; KPV calms inflammation. In gut protocols they are complementary — one rebuilds the lining while the other dampens the inflammatory signal. Neither has strong human RCT data.
Evidence quality
BPC-157
Preclinical onlyDozens of rodent and rat studies, mostly from a single Croatian research group (Sikiric and colleagues) that has been investigating this peptide since the 1990s. The replication base outside that group is thin. No completed human RCTs are in the public literature. Use anecdotal-plus-animal as your evidence floor, not as a substitute for the clinical trials that have not been done.
KPV
Limited human dataAnimal data is consistent across colitis, dermatitis, and wound-inflammation models. The human evidence base is small open-label IBD work, plus some topical dermatology studies. There are no completed RCTs at a regulatory scale. Treat the gut and skin anti-inflammatory claims as cautiously supported and the others as still speculative.
