KPV Peptide: The Anti-Inflammatory Fragment of a Pigmentation Hormone

KPV is three amino acids: lysine, proline, valine. It is the C-terminal fragment of alpha-melanocyte-stimulating hormone — the last three residues of a thirteen-residue hormone.

The interesting part is what gets left behind. Alpha-MSH drives pigmentation and has anti-inflammatory activity; KPV retains the anti-inflammatory association without the melanocortin receptor activity responsible for tanning.

The fragment logic

This is the same reasoning behind AOD-9604 — isolate the part of a molecule responsible for the effect you want, discard the rest. Here the aim is anti-inflammatory activity without pigmentation.

The contrast with melanotan II is instructive: both derive from the same hormone family, and they were pulled in opposite directions. One keeps the pigmentation activity, the other discards it.

What the research covers

• Inflammatory signalling. Work reports effects on NF-κB signalling and pro-inflammatory cytokine production in cell models.

• Gut. Much of the interest concerns intestinal inflammation, where KPV appears in research on colitis models.

• Skin and wound healing. It appears in the tripeptide wound-healing literature alongside GHK-Cu.

• Human trials. No published human dose-ranging or efficacy trial establishes an effective or safe dose.

The literature is preclinical, and the same caution applies as everywhere in this category: cell and rodent models establish a mechanism worth investigating, not a human dose.

Oral versus injected

KPV appears in research using oral and topical delivery as well as injection, particularly in gut-focused work where local delivery to the intestine is the point.

The vial math

KPV is supplied lyophilised, commonly in 10 mg vials, with figures discussed in the low milligram to microgram range.

As always, more diluent gives larger and more forgiving unit readings for small targets. The peptide calculator handles any combination.

Storage

Storage is the same as any reconstituted vial: 2–8 °C, protected from light, never frozen, and bounded by the shorter of peptide stability and the 28-day limit on bacteriostatic water. The bacteriostatic water guide covers the detail.

Frequently asked questions

Does KPV cause tanning?

The fragment lacks the melanocortin receptor activity responsible for pigmentation in the parent hormone, which is the reason it was separated out.

Is KPV in the KLOW blend?

Yes — KPV is the component that distinguishes KLOW from GLOW, typically at 10 mg.

Is oral KPV equivalent to injected?

No, and they should not share a dose figure. Different routes mean different bioavailability and, for gut-focused work, a different intended site of action.
