KPV: What It Is and Its U.S. Regulatory Status

What is KPV?

KPV is a very short peptide made of three amino acids: lysine, proline and valine. This sequence forms the tail end, or C-terminus, of alpha-melanocyte-stimulating hormone (alpha-MSH), a natural hormone involved in skin pigmentation and immune signaling.

KPV has been examined in laboratory and animal research on inflammation. Unlike full-length alpha-MSH, it is not expected to affect skin pigment. Research in people is very limited.

U.S. regulatory status

Current status: Not FDA-approved.

This means the FDA has not approved KPV as safe and effective for any medical use. No product containing it is an approved medicine in the United States.

KPV is sometimes included in multi-peptide blends sold under brand-style names. Those blends are not approved either.
