KPV
Anti-Inflammatory TripeptideAlso known as: Lys-Pro-Val · Alpha-MSH(11-13)
A C-terminal tripeptide of alpha-MSH with potent anti-inflammatory activity via NF-kB inhibition. Used orally or by injection for gut inflammation & systemic inflammatory conditions.
Typical Dose
500 mcg–1 mg 2x/day (oral); 250–500 mcg 1–2x/day (SubQ)
Route
Oral (for gut) or subcutaneous injection (for systemic)
Cycle
4–8 weeks
Half-life
Short (tripeptide; rapidly cleared)
Storage
Lyophilized: room temp. Reconstituted: 2–8°C, use within 30 days.
Overview
KPV is the C-terminal tripeptide (Lys-Pro-Val) of alpha-MSH, corresponding to residues 11–13. Despite its minimal size, it retains the full anti-inflammatory activity of alpha-MSH via melanocortin receptor-independent inhibition of NF-kB signaling in inflammatory cells.
Its extremely small size allows oral bioavailability (unusual among peptides) — it resists GI degradation better than most peptides & can reach intestinal tissue after oral administration. This makes it uniquely useful for gut inflammation conditions (IBD, colitis) where targeted delivery to intestinal mucosa is desired. Systemic inflammation can also be addressed via SubQ injection.
Quick Start Guide
Oral: 500 mcg–1 mg dissolved in water, twice daily on empty stomach (gut-targeted).
SubQ: 250–500 mcg once or twice daily near site of inflammation.
Research Indications
Gut inflammation (IBD, colitis)
Most EffectiveOral bioavailability allows direct delivery to intestinal mucosa. Inhibits NF-kB in gut epithelial cells. Animal models of colitis show significant anti-inflammatory benefit.
Systemic inflammation
EffectiveNF-kB inhibition across multiple tissue types. Broad anti-inflammatory without immunosuppression.
Skin inflammation
ModerateTopical & injected KPV studied for psoriasis & wound healing. Reduces inflammatory cytokines at the site of application.

Peptide Interactions
Both have gut repair & anti-inflammatory activity. BPC-157 drives epithelial repair via GH receptor upregulation; KPV inhibits NF-kB. Complementary mechanisms.
Side Effects & Safety
Common
- Minimal. Well-tolerated in animal & limited human studies.
Uncommon
- Mild injection site redness (SubQ route)
When to Stop
- Signs of allergic reaction
How to Reconstitute
Reconstitute with water for oral use or BAC water for SubQ.
Oral: dissolve in 10–20 mL water & consume.
SubQ: standard reconstitution as with other peptides.
Dosing math: Very small peptide. Typical: 1 mL BAC water per 1–2 mg vial. Oral solution can be more dilute.
Quality Indicators
Good — use as normal
- Clear, colorless solution
Discard immediately
- Particulate
- Discoloration
What to Expect
Week 1–2
Anti-inflammatory effect begins rapidly given NF-kB inhibition. IBD symptoms may begin to improve within days of oral administration.
Week 3–8
Continued gut mucosal healing (in IBD protocols). Systemic inflammatory markers improving.
