KPV (Lys-Pro-Val tripeptide)
KPV peptide, KPV acetate, Lysyl-prolyl-valine, alpha-MSH (11-13), α-MSH 11-13
Forms: Injectable 'research' powder, often sold inside multi-peptide 'recovery' blends.
A three-amino-acid fragment (Lys-Pro-Val) of the hormone alpha-MSH, sold as an anti-inflammatory 'research' peptide. All evidence comes from cells and mice; it has never been tested in people.
Legal status: Not approved anywhere; sold as a 'research chemical'. A 2026 FDA advisory panel backed US compounding, which is not an approval. Banned in sport at all times (WADA S0).
What it gives
What people use it for and what the sources report. Strength is a general category from the literature: mild, clear or strong.
Purpose
Promoted in bodybuilding and gym circles for inflammation, recovery and gut problems, often in blends with BPC-157 and TB-500. In mice with colitis it reduced gut inflammation; there are no human trials, and it is not approved as a medicine anywhere.
What people seek and what studies show
People hope for less joint and tissue inflammation, faster recovery and a calmer gut. In cell studies KPV entered cells through the PepT1 transporter and damped the NF-κB inflammatory pathway; in mice with chemically induced colitis it reduced inflammation and weight loss. The FDA found no human exposure data for any route, so its effect on joints, muscles or recovery in people is unknown.

Possible side effects
Possible does not mean certain: whether they appear depends on dose, duration, individual response and monitoring. Below — what to watch for and how to notice it early.

How to lower the risks
General ways to lower the chance of each side effect. No measure removes a risk completely.
Products obtained without a prescription are often fake, mislabeled or non-sterile, and there is no way to check at home. For legal supplements, look for third-party testing (Informed Sport, NSF).
What is unknown cannot be lowered, only avoided; tell your doctor what you have taken.

“KPV is a proven anti-inflammatory that heals joints and the gut.”
Its effects were shown in cells and in mice with colitis; there is no human trial, and the FDA found no human data at all.
