What Is KPV? The Alpha-MSH Tripeptide Explained
KPV is a synthetic tripeptide (lysine-proline-valine) matching the C-terminal fragment of alpha-MSH, sold for laboratory research use only. Here is what it is and how to verify a COA.
KPV is a tripeptide made of three amino acids, lysine, proline, and valine. It is the C-terminal fragment of the larger hormone alpha-melanocyte-stimulating hormone (alpha-MSH). It is sold for laboratory research use only.
Where KPV comes from
KPV represents the final three amino acids of alpha-MSH. As a three-residue sequence it is far shorter than the 13-amino-acid parent hormone, and vendors sell it as a separate compound.
Research-use status
Published literature on KPV is mostly cell and animal work, and this page does not summarise effects or uses. It is not an approved drug.
COA considerations for KPV
Because KPV is a very short, well-defined peptide, mass spectrometry can confirm its identity precisely and HPLC can establish purity. A credible COA names the lab and reports a specific purity figure. For injectable research preparations, endotoxin and sterility results add assurance.
What to check before buying
Look for a named lab, a decimal purity percentage that matches the product, a recent test date, and a verification key or portal. Vague purity claims with no lab named are not independent evidence.
Frequently Asked Questions
What does KPV stand for?
KPV is the single-letter notation for its three amino acids: K (lysine), P (proline), and V (valine). It is the C-terminal fragment of alpha-MSH.
Is KPV a steroid or hormone?
No. KPV is a small peptide fragment. It is derived from a hormone (alpha-MSH) but is itself a three-amino-acid peptide sold for laboratory research use only.
How is KPV verified on a COA?
By mass spectrometry for identity and HPLC for purity, reported by a named third-party lab, ideally with endotoxin testing for injectable research preparations.
