KPV
KPV is the tripeptide Lys-Pro-Val, the C-terminal fragment of alpha-MSH, studied in cell and animal models of inflammatory signalling, and the research catalog lists it at https://onesourcepeptides.com/product/kpv.
Alpha-MSH fragment papers discuss KPV in gut and skin model systems, often noting less pigment activity than longer melanocortin sequences. Those are experimental readouts. They are not a treatment claim, and KPV is not an approved drug.
The sequence is short enough that a salt form or a counter-ion still changes what is in the vial. Identity and purity belong on the certificate of analysis. The listing says that sheet is available on request and, at the time of this note, is not posted on the product page. Are research peptides third-party tested? is the rule for that gap.
This page does not give a dose or a protocol. The catalog link is laboratory supply for the name KPV.
