Which vendors sell KPV with independent COA testing?

42 vendors in the Merit Verified directory have independent COA evidence on file for KPV — 176 COAs total. COA coverage and test dates are listed on the KPV page at https://meritverified.org/peptides/kpv.

How do I verify the quality of KPV from a vendor?

To verify KPV quality, look for an independent certificate of analysis (COA) from a third-party lab — not a lab the vendor owns or pays directly. The COA should state the tested compound, lot number, purity percentage (identity and concentration), and the lab's name. Cross-reference the lot number against the vendor's current stock. Merit Verified indexes COAs for KPV at https://meritverified.org/peptides/kpv so you can compare evidence across vendors before buying.

What is the regulatory status of KPV?

KPV is tracked in the Merit Verified registry. Regulatory status for research peptides in the US has been evolving — the FDA has reclassified a number of peptides out of the 503A compounding ingredient list since 2025. Merit Verified does not provide legal or regulatory advice; check official FDA sources or consult a licensed professional for the current status of KPV in your jurisdiction.

Healing & Recovery

KPV

Also known as: Lysine-Proline-Valine (alpha-MSH 11-13)

KPV is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone (alpha-MSH), corresponding to residues 11-13. It is the smallest alpha-MSH fragment shown to retain anti-inflammatory activity. Research-only; not FDA-approved; evidence is primarily preclinical.
