KPV is the C-terminal alpha-MSH(11-13) tripeptide; on-file CAS 67727-97-3 matches PubChem (also supplied as the acetate salt).

Regulatory status: As of 2026, KPV is not FDA-approved; KPV was nominated for the compounding bulk-substances list and placed in Category 2, but that nomination was later withdrawn by the nominator, with FDA noting a lack of human exposure data (FDA Category 2 page, current as of 04/22/2026).

Frequently asked

How much does KPV cost?
About $35–$100 per vial, depending on vial size. Compare the same size across vendors.
Why do KPV prices vary so much?
Vial sizes differ, so always compare the same vial size across vendors. Batch testing, stock, and pack discounts move the true cost too — see what "Verified" means.
How are KPV vendors verified?
A vendor earns a Verified badge only after independent batch testing (HPLC purity + mass-spec identity) checks out against its COA. Verification is never for sale.
