What is KPV peptide?

KPV is a tripeptide made of lysine, proline and valine. It’s the C-terminal end (residues 11 to 13) of alpha-melanocyte-stimulating hormone (α-MSH), and it keeps much of that hormone’s anti-inflammatory activity in research models. Our vial holds the capped form, Ac-Lys-Pro-Val-NH2, at about 384 g/mol. The caps protect a short peptide from breakdown.

Free KPV is about 342 g/mol, so listings differ depending on the form, and data should only be compared between the same form. KPV also appears in blends such as KLOW 80mg. Every lot is Made in China and tested by an accredited third-party lab, and it’s sold for laboratory research only. See the specs for our KPV peptide.
