The Short Answer
KPV is a tripeptide (three amino acids: lysine, proline, valine). It's the tail end of alpha-melanocyte-stimulating hormone (α-MSH), a natural hormone with anti-inflammatory effects.
The "benefits" you see online come mostly from cell and mouse studies of intestinal inflammation. There are no published controlled human trials of injectable or oral KPV. It is not FDA-approved for any use.
This is an educational guide. It doesn't give dosing advice. Talk with a licensed clinician about any treatment.
Claimed Benefits vs Evidence
| Claim | Evidence level |
|---|---|
| Calms gut inflammation (colitis, IBD) | Mouse and cell studies (Dalmasso 2008; Kannengiesser 2008) |
| Absorbed by gut cells | Cell and mouse studies show uptake through the PepT1 transporter |
| Skin inflammation, psoriasis | Mostly extrapolated from α-MSH biology; little direct data |
| Wound healing, "immune support" | Marketing claims; no human trials |
| Gut health in healthy people | Not studied |
What the Key Studies Did
- Dalmasso et al., Gastroenterology 2008: KPV entered intestinal cells through PepT1, lowered inflammatory signaling, and reduced the severity of chemically induced colitis in mice.
- Kannengiesser et al., Inflamm Bowel Dis 2008: KPV reduced inflammation in two mouse models of IBD.
These are useful early signals. They don't show that KPV works or is safe in people, and they don't establish any human dose.
Why KPV Shows Up in Blends
KPV is one of the components in the KLOW blend (alongside GHK-Cu, BPC-157 and TB-500). Its inclusion is based on the anti-inflammatory theory above, not on human trials of the blend. See our GLOW vs KLOW guide.
Quality and Safety
Because KPV isn't an approved drug, products are sold without FDA oversight of identity, purity or sterility. Human side effects haven't been systematically studied. A licensed clinician can help you weigh that uncertainty.
Tracking With Your Clinician
If you're working with a clinician on gut or inflammatory symptoms, consistent notes help: symptoms, meals, flare days and anything you're taking. PeptIQ.io keeps that on one timeline you can share with your care team.
