Description

KPV (α-MSH(11-13) tripeptide) is a tripeptide fragment (Lys-Pro-Val) of alpha-melanocyte-stimulating hormone. It is studied in anti-inflammatory and gastrointestinal research models.

What researchers study

  • Anti-inflammatory signaling research
  • Gastrointestinal and gut-barrier models
  • Melanocortin-pathway studies

Handling & storage

Supplied as a lyophilized powder for reconstitution with bacteriostatic water (not included). Store at −20 °C (−4 °F), protected from light. Every lot is independently tested against a 99%+ purity release target, and the batch Certificate of Analysis is published in full on this page.

Research Use Only (RUO). Not for human or animal consumption, nor for therapeutic, diagnostic, or cosmetic use; to be handled only by qualified professionals in a controlled research setting.

Identity and specification

KPV is also referred to as Lysine-Proline-Valine and α-MSH (11-13). It has the molecular formula C16H30N4O4 and a molecular weight of 342.43 g/mol (CAS 67727-97-3). That weight is corroborated by the mass-confirmation peak on this product’s own certificate rather than quoted from a reference alone.

How this lot was tested

The KPV currently in stock measured 99.04% for the 10 mg (lot 261807), tested by Freedom Diagnostics. The full certificate is published on this site as a free download — including the raw chromatogram and mass spectrum, so the figure can be read off the underlying data rather than taken on trust.

We use two independent laboratories, and each certificate says which produced it. Vanguard Laboratory is ISO 17025:2017 accredited (A2LA certificate #6377.01.01) and reports chromatographic purity and net quantity with a stated measurement uncertainty. Freedom Diagnostics reports HPLC-UV purity together with LC-MS identity confirmation, which is what verifies the vial contains the compound on the label rather than merely a pure something. Two laboratories, two methods, both published — see how we test.

Commonly studied alongside

In the literature KPV is most often examined together with BPC-157, GHK-Cu and KLOW. Reconstitution is the same for all of them — see the reconstitution guide and the calculator, and the storage guide for how long reconstituted material holds. Current pricing for every compound and size is on the price list.

Common questions

What is the purity of your KPV, and can I see the test results?

Our current lot measures 10 mg at 99.04% purity by HPLC, tested by Freedom Diagnostics. The full certificate — including the raw chromatogram, net content and the lot number — is published on this page as a free download. No request or email needed.

Is KPV the same as Lysine-Proline-Valine?

Yes. KPV is also referred to as Lysine-Proline-Valine and α-MSH (11-13). They describe the same compound — the naming differs between suppliers, development literature and chemical nomenclature.

How is KPV reconstituted?

KPV ships lyophilized — a freeze-dried solid — and is reconstituted with bacteriostatic water, which is sold separately. Add the water slowly down the inside wall of the vial rather than directly onto the powder, then swirl gently; do not shake. The final concentration depends on how much water you add, and our reconstitution calculator works out the volume for a target concentration.

How should KPV be stored?

Lyophilized vials are stored at −20°C (−4°F), protected from light, and are stable at ambient temperature for the length of a normal shipping transit. Once reconstituted, keep refrigerated and protected from light. See our storage and stability guide for detail on how long reconstituted material holds.

How fast do you ship KPV, and do you ship internationally?

Orders leave Miami within 1–2 business days of payment clearing. US delivery is typically 2–5 business days and shipping is free over $150. We ship worldwide — Canada, Europe including the UK, and the rest of the world at flat regional rates. Everything travels in insulated packaging with a cold pack, in a plain outer box with no branding.
