Research background

About KPV

KPV is the last three residues of alpha-melanocyte-stimulating hormone (α-MSH): lysine, proline and valine. The tripeptide is studied for the anti-inflammatory activity described for α-MSH, without the hormone's pigment-related receptor effects, which makes it the smallest piece of the melanocortin system that inflammation researchers work with.

A 2008 review in Endocrine Reviews by Brzoska and colleagues covers α-MSH and its related tripeptides. In gut research, Dalmasso et al. (2008) showed that intestinal cells take KPV up through the transporter PepT1, and later work packed it into nanoparticles for targeted delivery in mouse models (Xiao et al., 2017). On our site KPV is in Recovery & repair and in the specialty-peptides category.

KPV FAQ

Why order endotoxin testing with KPV?

KPV is mostly used with inflammation readouts — cytokine panels, NF-κB reporters, macrophage assays — and bacterial endotoxin switches on the same readouts. Endotoxin testing is available on request and listed on the COA when tested, so ask for it with your quote.

Is KPV the same as α-MSH?

No. α-MSH is the full hormone; KPV is only its last three residues, with its own CAS number (67727-97-3) and a molecular weight of 342.44 g/mol.

How to order

Ordering KPV from Medabol

Kit and minimum: KPV is sold by the kit: 10 vials of one specification (5 mg, 10 mg and 20 mg). The minimum is 1 kit per SKU, so an individual buyer can order a single kit and a lab can order many.
Price: Reference prices are listed per kit above, from $78.20. The kits of your whole quote list count together — 5–19 kits are 20% off every kit, and from 20 kits our sales team quotes the price — so KPV adds up with anything else you order; your written quote has the final price.
Documents: Every lot has its own COA with HPLC purity and MS identity; the order ships with the certificate of its lot, and our sales team sends it before you order if you ask.
Shipping: Orders ship from China by international express courier. Shipping from $80 per order; the written quote confirms the exact charge for your destination.
Payment: Nothing is paid on this website. After you send your quote list, a sales representative confirms the amount and shipping on WhatsApp or by email and tells you in that chat how to pay.
Research goal: Listed under Recovery & repair — BPC-157, TB-500, their blends and immune-signalling peptides.
