KPV
A tripeptide fragment of alpha-MSH, studied for anti-inflammatory signaling independent of pigmentation effects.
Overview
KPV is the C-terminal tripeptide fragment of alpha-melanocyte-stimulating hormone (α-MSH). Researchers identified that this small fragment retains α-MSH’s anti-inflammatory activity without the pigmentation and appetite effects associated with the full hormone or compounds like Melanotan, making it a focus of gut- and skin-inflammation research.
Mechanism of Action
Unlike full-length α-MSH, KPV’s anti-inflammatory activity appears to occur largely independent of melanocortin receptor binding. Research has focused on its ability to inhibit NF-κB signaling, a central pathway in inflammatory gene expression, and to modulate cytokine production in models of gut and dermal inflammation.
Cited Research
NF-κB pathway inhibition
Studied for suppressing this central inflammatory-signaling pathway independent of melanocortin receptors.
Gut inflammation models
Examined in colitis and inflammatory bowel disease animal models.
Dermal inflammation research
Studied for anti-inflammatory effects in skin-irritation and wound models.

Safety & Handling
KPV should be handled only by qualified personnel in a laboratory setting, stored and reconstituted per its Certificate of Analysis, and kept refrigerated once reconstituted. It is not evaluated or approved by the FDA for any human or veterinary use.
Frequently Asked Questions
Is KPV related to Melanotan?
They’re both derived from the same parent hormone (α-MSH), but KPV is just the smallest active fragment and doesn’t carry the pigmentation-related activity that Melanotan analogs are studied for.
What’s the difference between the vial and capsule form?
Both are the same peptide sequence; the vial is a lyophilized powder for reconstitution, while the capsule form is pre-formulated for oral-route research protocols.
Is KPV legal to purchase?
It’s legal to sell and purchase as a research chemical for laboratory use in the U.S. It is not approved by the FDA as a drug or supplement for human consumption.
Is this page medical advice?
No. This page summarizes published literature for research and educational context only. It does not recommend a dose, protocol, or use in humans or animals outside a laboratory setting.
