KPV

Lysine-Proline-Valine

Also known as: KPV Tripeptide, Alpha-MSH Fragment 11-13

Overview

A tripeptide fragment from the C-terminus of alpha-melanocyte stimulating hormone (alpha-MSH). Possesses potent anti-inflammatory and antimicrobial properties without melanogenic effects. Particularly relevant for immune regulation in gut and mucosal tissues.

Half-Life
~30 minutes
Typical Dose
200–500 mcg
Frequency
1-2x daily
Cycle Length
4-12 weeks

Administration

SubcutaneousOralTopical

Benefits

  • Potent anti-inflammatory without broad immunosuppression
  • Reduces intestinal mucosal inflammation
  • Direct antimicrobial activity against bacteria and Candida
  • Modulates innate immune response in gut epithelium
  • Crosses the blood-brain barrier for neuroinflammation reduction
  • Supports immune homeostasis in chronic inflammatory conditions

Side Effects

  • Injection site redness (mild)
  • Slight fatigue (rare)
  • GI discomfort with oral use (uncommon)

Mechanism of Action

  • Inhibits NF-kB nuclear translocation and transcriptional activity
  • Reduces pro-inflammatory cytokine secretion (TNF-alpha, IL-6, IL-1-beta)
  • Enters colonic epithelial cells to directly suppress inflammasome activation
  • Modulates MAPK signaling pathways in immune cells
  • Exhibits direct membrane-disrupting antimicrobial activity

Contraindications

  • Pregnancy or breastfeeding
  • Active immunosuppressive therapy
  • Autoimmune conditions (consult physician)

Storage & Reconstitution

Store at 2–8°C (36–46°F) for up to 3 months. For long-term storage, keep at -20°C (-4°F). Once reconstituted, refrigerate and use within 2 weeks. Oral capsules: store in a cool, dry place.

Common peptide amounts:5 mg

Research Summary

Studied in preclinical models of inflammatory bowel disease, colitis, and skin inflammation. Demonstrated efficacy comparable to standard anti-inflammatory treatments in murine IBD models. Strong in vitro evidence for NF-kB inhibition. Cross-reference: see kpv in healing-recovery for tissue repair context.
