The short version

The C-terminal tripeptide of α-MSH — retains anti-inflammatory properties without pigmentation. Popular for IBD, SIBO and inflammatory gut/skin conditions. Key fact: Human data are limited: small trials or case-series reports exist, without large randomized studies. Preclinical IBD models show reduced colon inflammation; dermatology studies for wounds/psoriasis. Status: research chemical. Not approved; available as research chemical and via compounding pharmacies.

Identity & type

Molecular type
peptide
Origin
The C-terminal tripeptide of α-MSH — retains anti-inflammatory properties without pigmentation.

Mechanism of action

Enters cells via the PepT1 transporter, inhibits NF-κB and MAPK inflammatory pathways, reduces IL-8/TNF-α.

not confirmed in humans

Dosing & routes

Official / clinical context

No approved official document exists for KPV. Any protocols mentioned are to be read as information, not as a recommendation.

Regulator-approved labeling and published study designs — never a recommendation.

Community-reported practice

Orally 250–500 mcg 1–2× daily for gut; SC 200–500 mcg; topically for skin/wounds. The community reports calming of IBD/Crohn's symptoms, skin inflammation (psoriasis, eczema) and a mild general anti-inflammatory tone; popular both orally and topically.

Unverified self-reports. Not medical advice. Not endorsement.

Expected effects (community)

The community reports calming of IBD/Crohn's symptoms, skin inflammation (psoriasis, eczema) and a mild general anti-inflammatory tone; popular both orally and topically.

Protocol — official vs community

Official / label

No approved product. Alpha-MSH fragment (Lys-Pro-Val) studied in inflammatory models; human data thin.

Duration: Study use only.

The anti-inflammatory tail of the melanocortin system without the pigmentation.

Community (anecdotal)

Oral capsules (200–600 mcg) or 100–300 mcg SC daily for gut/inflammation protocols.

Cycle:
4–8 weeks.
Break:
4 weeks.

Oral-first routing is the community norm — unusual and sensible for a peptide with gut-indication anecdotes.

Human evidence

Human data are limited: small trials or case-series reports exist, without large randomized studies. Preclinical IBD models show reduced colon inflammation; dermatology studies for wounds/psoriasis.

Preclinical evidence

Preclinical IBD models show reduced colon inflammation; dermatology studies for wounds/psoriasis.

Known risks

  • Very mild; rare GI upset.characterized
  • Unregulated injectable supply — sterility, purity and accurate dose not assuredtheoretical

Teal: characterized in clinical/labeling contexts. Amber: theoretical or reported outside controlled settings.

Unknowns & evidence gaps

  • Long-term human safety
  • Optimal dose and pharmacokinetics
