Alpha-MSH C-terminal tripeptide3 amino acids

KPV is a tripeptide derived from the C-terminal sequence of alpha-melanocyte stimulating hormone (alpha-MSH). Research suggests potent anti-inflammatory activity without the pigmentation effects of the parent hormone.

Mechanism of Action

Enters cells and inhibits NF-kB nuclear translocation, reducing inflammatory cytokine production (IL-1beta, IL-6, TNF-alpha). Acts intracellularly rather than through melanocortin receptors.

Benefits

  • Potent anti-inflammatory effects in cell studies[1]
  • Reduced colitis severity in animal models[1]
  • No melanocyte stimulation or tanning effects[1]
  • Antimicrobial properties against S. aureus[1]

KPV - Dosing in Published Research

Reported routes: Oral, Subcutaneous injection, Topical
Research dosing not established for humans. Animal studies typically used 100-400 mcg doses. Explored in both injectable and oral formats.

The dosing information above is sourced from published research literature and clinical trials. These are not recommendations. Individual responses vary. Always consult a healthcare provider before considering any peptide-based therapy.

Side Effects

  • Very limited human data[1]
  • Unknown systemic safety profile[1]
  • Potential GI effects with oral use[1]
  • Unknown drug interactions[1]
