KPV

KPV (Lys-Pro-Val)

The gut anti-inflammatory

A tripeptide derived from the C-terminal end of alpha-melanocyte-stimulating hormone (alpha-MSH). KPV retains the potent anti-inflammatory properties of the parent hormone without melanogenic (skin-darkening) effects. It targets gut inflammation through MC1R signaling and NF-kB suppression, making it a focused tool for IBD, colitis, and intestinal permeability.

Typical dose
200–500 mcg/day
Availability
Research-only

Key Benefits

01

Reduction of intestinal inflammation and mucosal damage

02

Preservation of gut barrier integrity (tight junctions)

03

Suppression of pro-inflammatory cytokines in the gut

04

Potential relief from IBD and colitis symptoms

Mechanism of Action

How KPV works

KPV reduces gut inflammation through targeted molecular pathways:

  • MC1R activation — binds melanocortin-1 receptor on intestinal epithelial cells and macrophages, triggering an anti-inflammatory signaling cascade that dampens mucosal immune overactivation
  • NF-kB inhibition — directly suppresses nuclear translocation of NF-kB, the master transcription factor driving inflammatory cytokine production (TNF-alpha, IL-1beta, IL-6) in the gut
  • Epithelial barrier support — preserves tight junction protein expression (claudin-1, occludin, ZO-1) under inflammatory stress, reducing intestinal permeability ("leaky gut")
  • Macrophage polarization — shifts intestinal macrophages from pro-inflammatory M1 to anti-inflammatory M2 phenotype, promoting tissue resolution rather than chronic inflammation

Your Genetics & KPV

Genetic variants that affect your response

These SNPs determine how effectively KPV works for you specifically. A genetic peptide report identifies your variants before you start.

MC1Rrs1805008
Melanocortin signaling

The Arg160Trp variant reduces MC1R function. Since KPV acts through MC1R, carriers of loss-of-function variants may have a diminished anti-inflammatory response and could require higher doses or alternative stacking strategies.

NOD2rs2066844
Innate immune sensing

NOD2 variants are the strongest genetic risk factor for Crohn's disease. Carriers have dysregulated mucosal immunity — KPV's NF-kB suppression targets exactly this pathway, potentially offering proportionally greater benefit.

FUT2rs601338
Gut mucosal defense

Non-secretors (AA genotype) lack fucosylated glycans on the gut mucosa, altering microbiome composition and increasing susceptibility to gut inflammation. KPV's barrier-protective effects may be especially valuable for non-secretors.

IL10rs1800896
Anti-inflammatory signaling

The -1082A>G variant affects IL-10 production. Low IL-10 producers (AA genotype) have reduced natural anti-inflammatory capacity — KPV's M2 macrophage polarization may partially compensate for this deficit.

Sourcing & access

Where to buy KPV

KPV is sold as a research compound, not a licensed medicine, so quality and legal status vary widely by country and vendor. If you're sourcing it, treat independent purity testing as non-negotiable.

  • Insist on a recent third-party Certificate of Analysis (COA) for the exact batch — labs like Janoshik verify purity and identity.
  • Check the legal status where you live before ordering — it differs from country to country.
  • Reconstitute correctly with bacteriostatic water and start at a conservative dose.

Common Stacks

KPV is commonly combined with:

BPC-157

Gut Healing StackModerate Evidence

Body Protection Compound 157

A 15-amino-acid peptide derived from human gastric juice. The most-researched peptide for tissue repair, gut healing, and injury recovery. Works through nitric oxide signaling, angiogenesis, and collagen stimulation.

GLP-2

Gut Restoration StackModerate Evidence

Glucagon-Like Peptide-2

A 33-amino-acid peptide produced by intestinal L-cells. GLP-2 is the body's primary signal for intestinal growth and repair. Its analog teduglutide (Gattex) is FDA-approved for short bowel syndrome. GLP-2 stimulates crypt cell proliferation, increases villus height, enhances nutrient absorption, and restores gut barrier function.

Frequently Asked Questions

What is KPV used for?

KPV is used primarily for gut inflammation — conditions like IBD, ulcerative colitis, and intestinal permeability (leaky gut). As a fragment of alpha-MSH, it delivers potent anti-inflammatory effects specifically in the gut via MC1R receptor activation and NF-kB suppression, without the skin-darkening effects of full-length melanocortin peptides.

Does genetics affect KPV response?

Yes. MC1R variants directly affect the receptor KPV binds to — loss-of-function variants may reduce response. NOD2 variants (linked to Crohn's disease) indicate dysregulated gut immunity that KPV specifically targets. FUT2 secretor status affects gut mucosal defense and microbiome composition, influencing baseline gut vulnerability.

Can KPV be taken orally?

KPV is one of the few peptides being explored for oral delivery. As a tripeptide, it is small enough to potentially survive partial digestion, and its target (intestinal epithelium) is directly accessible via oral route. Some practitioners use oral KPV specifically for gut conditions, though bioavailability data is still limited.
