KPV

Immune Modulation

KPV (Lys-Pro-Val) is a tripeptide derived from alpha-MSH with strong anti-inflammatory, antimicrobial, and antifungal properties. It is being explored for use in inflammatory bowel diseases, topical inflammatory skin conditions, and systemic inflammation. Multiple delivery routes have been studied, including oral, SubQ, and topical forms.

Protocol Summary

Oral: Daily · Dose range 100–500 mcg with gradual titration
Subcutaneous (SQ): daily · Dose range 100–500 mcg with gradual titration
Cycle Length: 4–8 weeks typical; reassess before extending

Frequency & Cycling

Oral

Typical dose: 250–500 mcg/day in capsule form. Can be taken long-term under supervision for chronic gut inflammation.

Subcutaneous (SQ)

200–400 mcg daily SubQ recommended for systemic anti-inflammatory effects. Use in 4–8 week cycles with evaluation.

Topical

Apply 2% KPV cream to affected skin areas twice daily. Safe for continuous use in inflammatory skin conditions.

Potential Benefits & Use Cases

KPV is a research-use-only compound not approved for therapeutic application.
Reduces pro-inflammatory cytokines and modulates immune responses in IBD models (preclinical)
Enhances epithelial cell regeneration and tight junction integrity — supports gut barrier function (preclinical)
Multiple routes of administration show activity (oral and subcutaneous) (preclinical)
Supports wound healing through inflammatory modulation (preclinical)
Does not affect melanocyte activity or skin pigmentation unlike full α-MSH (preclinical)
Clinical data Strong preclinical Limited data

Mechanism of Action

→Inhibition of NF-kB activation, blocking inflammatory cascade
→Reduction of pro-inflammatory cytokines such as IL-6 and TNF-α
→Supports mucosal immunity and barrier restoration

Lifestyle & Optimization

timing

Consistent dosing schedule. Oral for gut, SubQ for systemic.

diet

Anti-inflammatory diet (omega-3s, polyphenols, minimal processed foods). Support gut microbiome diversity.

exercise

Moderate exercise.

sleep

Sleep 7–9 hours. Stress management.
