KPV is one of the smallest peptides out there, just three amino acids (lysine, proline and valine). It’s a piece of a natural hormone called alpha-MSH, and researchers study it mostly for inflammation. It comes as a freeze-dried powder in a 10 mg vial.
KPV, supplied to Canadian researchers by Popular Peptides. One 10 mg vial, ≥99% purity, molecular weight 342.4 g/mol. Tested by an independent lab for purity and content (HPLC); the lab report (COA) for your batch is available on request. Ships tracked and insured from Vancouver by Canada Post Xpresspost, usually 1 to 4 business days, with no customs step and no brokerage fee.
Sold as a laboratory research material only, for in vitro use. It isn’t a medicine and isn’t meant for people or animals.

KPV — compound background
Tripeptide (Lys-Pro-Val), alpha-MSH C-terminal fragment
KPV is the three-residue C-terminal tail of alpha-melanocyte-stimulating hormone. It retains the anti-inflammatory character associated with the parent hormone while lacking the melanocortin-receptor region responsible for pigmentation — the reason it is studied for inflammation without a tanning effect.
Solubility & reconstitution
Extremely water-soluble — a tripeptide has essentially no structure to resist dissolution. Solutions are clear and colourless and form almost instantly.
Solubility is effectively unlimited at working concentrations.
Storage
Sealed powder stable at -20 °C. Refrigerate at 2-8 °C.
Commonly worked with for 3-4 weeks at 2-8 °C.
Stability
None of the peptide oxidation or isomerisation routes are significant at this size; the practical risks are container-level, not molecular.
Reading the Certificate of Analysis
Confirm the mass near 342.4 Da. At this small size, net peptide content versus salt weight is worth checking, since the counterion is a larger fraction of the vial mass than for longer peptides.
