Peptides for gut health: what the evidence says
BPC-157 comes from a protein in stomach juice and was first studied for ulcers and inflammatory bowel disease. KPV, a fragment of the hormone alpha-MSH, is promoted for gut inflammation.
This page has not yet been reviewed by a credentialed medical professional. It is educational and is not medical advice.
Both have animal and cell research on gut inflammation. BPC-157 entered early clinical testing for bowel disease decades ago but was never approved, and KPV has no controlled human trials.

Common questions
Does BPC-157 help with IBD or leaky gut?
It was studied in rat models of gut injury and entered early clinical trials for bowel disease under the code PL 14736, but it has never been approved and published human results are lacking.
Is KPV proven for gut inflammation?
No. The evidence is from cell and animal studies; no controlled human trials were found.
