// Overview

What is KPV?

KPV (Lysine-Proline-Valine) is the C-terminal tripeptide fragment of alpha-melanocyte-stimulating hormone (α-MSH). Despite being only three amino acids long, KPV retains the full anti-inflammatory potency of the parent hormone while lacking the melanogenic (tanning) and other melanocortin receptor-mediated effects.

KPV’s primary mechanism is the inhibition of NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells), the master transcription factor controlling the inflammatory response. By preventing NF-κB translocation to the nucleus, KPV broadly suppresses the production of pro-inflammatory cytokines including TNF-α, IL-1β, and IL-6.

This peptide has shown particular promise for inflammatory bowel disease (IBD), with studies demonstrating that oral and colonic administration of KPV significantly reduces intestinal inflammation. It is also being explored for skin inflammatory conditions, autoimmune disorders, and as a general anti-inflammatory agent.

// How It Works

How KPV Works

KPV exerts potent anti-inflammatory effects through NF-κB inhibition:

  1. NF-κB inhibition — Prevents the nuclear translocation of NF-κB by stabilizing the IκBα inhibitor complex. This blocks the master inflammatory switch at its source.
  2. Cytokine suppression — Downstream of NF-κB inhibition, KPV reduces production of TNF-α, IL-1β, IL-6, IL-8, and other pro-inflammatory mediators.
  3. Intestinal epithelial protection — In gut tissue, KPV has been shown to enter intestinal epithelial cells and directly interact with inflammatory signaling cascades, reducing colitis.
  4. PepT1 transporter uptake — KPV is actively transported into intestinal cells via the PepT1 peptide transporter, which explains its oral bioavailability for gut-targeted effects.
  5. No immunosuppression — Unlike corticosteroids, KPV calms excessive inflammation without broadly suppressing immune function.

Dosage Information (User-Reported)

Disclaimer: Dosage information is compiled from user reports and published research. This is not medical advice. Consult a healthcare professional before use.
Level Dose Frequency Duration
Oral (GI Focus) 200-500 mcg 1-2x daily (capsule) 4-8 weeks
Subcutaneous 200-500 mcg Daily 4-8 weeks
Topical Applied to affected area 1-2x daily As needed

What to Expect

Week 1-2

GI symptoms begin improving if present. Reduced bloating and discomfort. Skin inflammation calming with topical use.

Week 3-4

Significant reduction in inflammatory symptoms. Gut function improving. Joint inflammation may decrease.

Week 5-8

Full anti-inflammatory effects. IBD/IBS symptoms substantially reduced. Skin conditions clearing. Systemic inflammation markers improving.

Note

Best results for gut issues with oral/capsule form. Injectable for systemic inflammation. Topical for localized skin conditions.
