Product Overview

KPV is a tripeptide made of three amino acids, lysine, proline, and valine, which together form the C terminal fragment of alpha melanocyte stimulating hormone (alpha-MSH). What makes KPV interesting to researchers is that this tiny fragment retains a portion of the parent hormone’s signaling activity without carrying the pigmentation activity that comes with the full sequence.

Each NXTSTATE vial contains 5mg of lyophilized powder, tested by an independent third party laboratory before it reaches inventory. The lab report for this lot is published on this page. Check it before you buy.

Research Background

KPV appears in published literature examining inflammatory signaling pathways, with research models focused on NF-kB and related cascades. Its very small size relative to most research peptides makes it a frequent subject in cellular uptake and delivery studies, since three amino acid chains behave differently from the longer sequences that dominate the category.

Researchers frequently study KPV alongside repair oriented compounds such as BPC-157. See our Research Notes for more.

Quality Assurance

Every lot is tested by an independent third party lab for identity, quantity, and purity by RP-HPLC with UV detection. We publish the actual report, not a badge and not a promise. You can read it on this page before you spend a dollar.

If a company will not show you the lab report before you buy, that tells you something. Ours is right here.

Reconstitution and Handling

This tripeptide is supplied as a lyophilized powder and is typically reconstituted with bacteriostatic water for laboratory use. Add solvent slowly against the vial wall and allow the powder to dissolve on its own without shaking. Store reconstituted material refrigerated and protected from light. Bacteriostatic water and syringes are available separately.

Why Researchers Study KPV

Size is the whole story with KPV. At three amino acids it is one of the smallest compounds in the research catalog, and that changes how it behaves in nearly every experimental model: uptake, stability, and handling all differ from the twenty and thirty residue chains that dominate this category. Researchers use KPV specifically because it separates the signaling fragment from the rest of the parent hormone.

That parent hormone, alpha-MSH, carries pigmentation activity that KPV does not, which is precisely why the fragment is studied on its own. Published KPV literature is indexed on PubMed under KPV peptide if you want to read the primary sources yourself.

Storage and Stability

The lyophilized powder is stable for extended periods when stored correctly. Keep unopened vials at -20C, protected from light, and let a vial reach room temperature before opening it so condensation does not form on the powder. Once reconstituted, the solution should be refrigerated at 2C to 8C and kept away from light. Avoid repeated freeze and thaw cycles, which degrade peptides faster than storage temperature alone.

Handle vials gently. Peptides in solution are sensitive to mechanical stress, so swirl rather than shake, and do not vortex the solution.
