KPV: what it is & how it’s tested
KPV is a tripeptide made of three amino acids — lysine, proline and valine. It corresponds to the C-terminal fragment of alpha-melanocyte-stimulating hormone (alpha-MSH). It is supplied lyophilised as a research compound for in vitro laboratory study only.
For in vitro laboratory research only. Not for human or animal consumption; not intended to diagnose, treat, cure or prevent any condition. 18+.

What KPV is
KPV is one of the shortest research peptides — a three-amino-acid sequence (Lys-Pro-Val). It is the tail-end fragment of the larger alpha-MSH peptide, and is manufactured and studied as a distinct short peptide.
Its short, defined sequence is confirmed by mass spectrometry and its purity measured by HPLC, so each batch can be reported on an independent Certificate of Analysis.
Where KPV appears in research
In the research literature, KPV and alpha-MSH fragments are studied in inflammation and immunology research models. This describes the research domain in which the compound appears, not a claim of any effect. KPV is not a medicine, supplement or cosmetic, and is not approved for human or veterinary use.
How KPV should be tested
Quality is a matter of evidence, not the label. A credible supplier tests every batch at an independent laboratory: HPLC measures purity as a percentage (commonly to a ≥99% benchmark), and mass spectrometry confirms the compound’s identity.
The result should be a batch-specific Certificate of Analysis you can verify at source. Learn how to read a COA, or see BioHack London’s independent KPV reports.
Storage, handling and reconstitution
Lyophilised (freeze-dried) KPV is generally kept cool, dry and out of light. Reconstitution — dissolving it in a suitable solvent such as bacteriostatic water — is done immediately before laboratory use, and the reconstituted solution is typically refrigerated and used within a limited period.
Our reconstitution calculator helps work out solvent volumes, and bacteriostatic water is available in the range.
KPV: frequently asked questions
What is KPV?
KPV is a tripeptide (lysine-proline-valine) corresponding to the C-terminal fragment of alpha-melanocyte-stimulating hormone (alpha-MSH). It is supplied as a lyophilised research compound for in vitro laboratory research use only.
Is KPV related to alpha-MSH?
Yes — KPV is the three-amino-acid C-terminal fragment of the larger alpha-MSH peptide. It is studied as a distinct short peptide in its own right.
How is KPV tested?
A credible supplier tests each batch at an independent laboratory — HPLC for purity (commonly to a ≥99% benchmark) and mass spectrometry to confirm identity — and publishes a batch-specific Certificate of Analysis you can verify at source.
Is KPV for human use?
No. KPV is supplied strictly for in vitro laboratory research. It is not for human or animal consumption and is not intended to diagnose, treat, cure or prevent any condition. Purchasers must be 18 or over.
