KPV vs BPC-157
Key differences, research and prices — side by side.
The key difference
KPV is a three-amino-acid fragment of alpha-MSH studied for calming inflammatory signaling, for example in colitis models. BPC-157 is a 15-amino-acid peptide studied mainly for tissue repair and blood-vessel growth. Both rest mostly on animal research.
| KPV | BPC-157 | |
|---|---|---|
| What it is | KPV is a tripeptide (lysine-proline-valine) that makes up the tail end of alpha-melanocyte-stimulating hormone (α-MSH). | BPC-157 (“body protection compound”) is a synthetic 15-amino-acid peptide based on a fragment of a protein found in human gastric juice. |
| How it works | It appears to calm inflammatory signaling inside cells (the NF-κB pathway) without the pigment-darkening effects of the full hormone. | Laboratory studies suggest it interacts with growth-factor and nitric-oxide signaling involved in blood-vessel formation (angiogenesis) and tissue repair, though its exact receptor target has not been identified. |
