Buy KPV UK — The Three Checks That Matter
KPV is a small synthetic tripeptide, and because it is small the checks are simple: the sequence (Lys-Pro-Val), the CAS number, and a batch COA that confirms both purity and identity.

1. Confirm the sequence and CAS
KPV is Lys-Pro-Val, CAS 67727-97-3, a fragment of α-MSH. Because the molecule is small, the risk of mislabelling between similar tripeptides is real — the catalogue entry should state the sequence and CAS, and the batch COA should confirm the identity by mass.
2. Purity and identity are two different tests
HPLC purity reports how pure the sample is relative to other components; LC-MS identity confirms the molecule is actually the target compound. A complete KPV record shows both.
3. Check the COA against the batch number
The lot number on the vial must match the lot on the certificate, and the certificate should be checkable independently — enter the lot number on a public batch-verification page and the record comes back with the purity, identity and test date for that specific batch.
How to order from Index Peptides
KPV is available as a 10mg vial, with the certificate of analysis published on the product page and every released batch checkable by lot number on the verify page. Order online at checkout, or request an invoice for lab and institutional orders.
