KPV
alpha-MSH-derived tripeptide studied for anti-inflammatory activity in gut and skin research.
Molecular reference
Research background
KPV is the compound researchers reach for when the topic is inflammation — especially in the gut and skin. It is a tiny three-amino-acid peptide (Lys-Pro-Val) taken from the tail end of the natural hormone alpha-MSH, and it keeps that hormone's anti-inflammatory character without its pigment-changing effects. Studies have examined it in models of gut inflammation (searched around IBD research) and skin and tissue repair.
Its small size and targeted anti-inflammatory profile make it a frequently studied companion to repair peptides like BPC-157.

Reconstitution
- Supplied as a lyophilized (freeze-dried) powder for laboratory reconstitution.
- Bacteriostatic water (0.9% benzyl alcohol) is the most common reconstitution solvent for multi-use research handling; sterile or acetic-acid solutions are used for specific compounds.
- Introduce solvent slowly against the vial wall rather than directly onto the powder, and allow it to dissolve without vigorous shaking.
- Use the reconstitution calculator to determine solvent volume for a target concentration in your protocol.
Storage & handling
- Lyophilized powder: store sealed at -20 °C for long-term stability; short periods at 2–8 °C are generally acceptable.
- Once reconstituted: refrigerate at 2–8 °C and protect from light; use within the compound-specific window noted on the COA.
- Avoid repeated freeze–thaw cycles of reconstituted solution.
- Keep away from direct light and heat at all times.
Purity & verification
Every Popular Peptides batch is third-party tested by HPLC and LC-MS with a published Certificate of Analysis (≥99% purity).
