What is KPV?
KPV: Lys-Pro-Val, the C-terminal tripeptide of alpha-MSH that suppresses NF-kB/MAPK inflammatory signaling and is taken up by inflamed gut cells via the PepT1 transporter. The sources cited here most often discuss it for: Gut inflammation, animal; Mucosal healing, mice; Skin inflammation, marketing claim. Evidence label: Preclinical.

Intriguingly, we found that HA-KPV-NPs exert combined effects against UC by both accelerating mucosal healing and alleviating inflammation.
Mouse model of ulcerative colitis using KPV packed in targeted nanoparticles (Mol Ther, 2017); not a human study.
What is KPV researched for?
The three outcomes most discussed for KPV in the sources below, as those sources report them. humanpeptides.fyi makes no claims of its own: a listed benefit can be unproven or can have failed in trials, and the label on each line says which.
What do researchers and users say about KPV?
FDA has not identified any human exposure data on drug products containing KPV administered via any route of administration.
FDA safety-risk summary for KPV, listed under nominated-but-withdrawn substances on its compounding safety-risks page (content current as of April 2026).
I've been using it for a couple of weeks. If you have excessive gas then it most likely won't change that, but if you're having a tun of inflammation in your gut then it will work really well.
Unverified self-report; the thread starter notes most available evidence is animal data and anecdotes.
What side effects of KPV are reported?
- Reported GI upset, bloating, diarrhea, headachesanecdotal Reddit1314
- Human dosing and safety unknown15
- FDA says it lacks important safety information on KPV, including whether it would cause harm in humans, because no human exposure data were identified.regulator statement11
- Product identity is uncertain: FDA staff told its advisory panel that these peptides lack a settled chemical form, so material sold under the same name can differ between suppliers.regulator review (advisory meeting)3
What do peptide guides say about KPV?
- Dr. Axe Dr. Axe classifies KPV as research only, with evidence limited to cells and animals. 16
- PepEdHub PepEdHub describes KPV as the last three amino acids of alpha-MSH, keeping its anti-inflammatory action without activating melanocortin receptors, and lists gut inflammation and IBD as its main research interest. 17
- PubMed In human gut and immune cells, very low concentrations of KPV blocked NF-kB and MAP kinase inflammatory signaling, and oral KPV reduced chemically induced colitis in mice. 4
- Sheppard (law firm analysis) FDA scientific staff recommended against listing KPV and six other peptides for compounding in 2026, citing unsettled chemical identity, but the advisory panel voted to recommend it anyway. 3

What is KPV researched for?
The sources cited on this page most often discuss three outcomes: Gut inflammation, animal; Mucosal healing, mice; Skin inflammation, marketing claim. Each line above shows what the source reports and how strong that evidence is.
What side effects of KPV are reported?
Reported in the cited sources: Reported GI upset, bloating, diarrhea, headaches; Human dosing and safety unknown; FDA says it lacks important safety information on KPV, including whether it would cause harm in humans, because no human exposure data were identified. The list is not complete, and few listed risks does not mean a compound is safe.
How strong is the evidence for KPV?
Evidence label: Preclinical. Animal + cell studies only; human use anecdotal.
What else is KPV called?
Names used for it include Lys-Pro-Val, lysine-proline-valine, tripeptide KPV.
Does humanpeptides.fyi recommend KPV?
No. humanpeptides.fyi makes no claims and no recommendations of its own. It summarizes and links to what others have published and posted. Nothing here is medical advice; talk to a licensed clinician.
