KPV

Research Use Only
peptideOralSubcutaneous injection

A tiny three-amino-acid peptide with serious anti-inflammatory power. It's especially effective for gut inflammation, making it a go-to for conditions like IBD and other inflammatory gut issues. Also helps calm down whole-body inflammation.

What to Expect

1

Week 1–2

Reduction in systemic inflammation markers. If targeting gut, mild reduction in bloating and discomfort. Anti-inflammatory effects beginning.

2

Week 3–6

Significant improvement in inflammatory gut conditions. Reduced skin inflammation (psoriasis, eczema). Improved mucosal barrier integrity measurable.

3

Week 8+

Sustained inflammation control. Gut barrier healing. Reduced frequency and severity of autoimmune flares. Improved overall immune balance.

Common Side Effects

Injection site irritationMild headacheTransient fatigue
Tolerance: None — anti-inflammatory mechanism does not develop tolerance
Cycling: 4-8 weeks on, 2-4 weeks off. Can be used longer for chronic inflammatory conditions.

Scientific Overview

KPV is a C-terminal tripeptide (Lys-Pro-Val) derived from alpha-melanocyte stimulating hormone (α-MSH). It retains the potent anti-inflammatory properties of α-MSH without melanotropic activity. KPV inhibits NF-κB nuclear translocation and reduces production of pro-inflammatory cytokines including IL-1β, IL-6, and TNF-α. It has demonstrated efficacy in inflammatory bowel disease models by reducing mucosal inflammation and promoting epithelial barrier integrity. KPV can cross cell membranes and directly interact with intracellular inflammatory signaling cascades.

Dosing

200-500 mcg oral or subq daily. Take it by mouth if you're targeting the gut specifically. Cycle for 4-8 weeks.

Practical Guide

Reconstitution

Mix 5mg vial with 1-2mL BAC water. Typical dose is 200-500mcg.

Storage

Refrigerate after reconstitution. Use within 21-30 days.

Injection Sites

Lower abdomenOuter thigh

Subcutaneous with insulin syringe. Oral capsules available for gut-targeted anti-inflammatory effects.

Timing

Once or twice daily. Morning and evening dosing for inflammatory conditions. Consistent timing.

Food

Oral: take on empty stomach for gut inflammation. Injectable: no food interactions.

Medical Considerations

Medical oversight recommendedNot safe during pregnancy

Contraindications

  • Pregnancy/nursing
  • Active immunosuppressive therapy (opposing mechanisms)

Drug Interactions

Immunosuppressants (KPV is anti-inflammatory, may alter immune balance)NSAIDs (additive anti-inflammatory effects)

Recommended Monitoring

  • Inflammatory markers (CRP, ESR) for efficacy tracking
  • GI symptoms log if treating gut inflammation
