KPV at a glance

KPV is the tripeptide lysine-proline-valine, the C-terminal end of alpha-melanocyte stimulating hormone. It keeps alpha-MSH’s anti-inflammatory activity without the pigment effects.

It’s small enough to be taken up by gut cells through the PepT1 transporter, which is why it’s studied in models of gut inflammation.

KPV in published research

Dalmasso and colleagues reported in Gastroenterology (2008) that KPV reduced inflammation in mouse colitis models and was taken up through PepT1.

Laroui and colleagues later packaged KPV in nanoparticles and saw similar effects in mice.

The full list of KPV papers is on PubMed, and most abstracts are free to read.

The biology behind KPV

Alpha-MSH calms inflammation through melanocortin receptors. KPV is its last three amino acids and keeps much of that anti-inflammatory activity.

Inside cells it lowers NF-kappaB signaling, the switch for many inflammatory genes. Gut cells take it up through the PepT1 transporter, which is why colitis models are where most of the work is.

How to mix KPV 4mg

With 4mg in the vial, common water volumes work out like this:

• 1mL of water: 4mg per mL
• 2mL of water: 2mg per mL
• 3mL of water: 1.33mg per mL

Use sterile bacteriostatic water and add it slowly, aiming at the glass instead of the powder. A gentle swirl is all it needs.

Dry vials last longest frozen at -20°C. Reconstituted solution goes in the fridge and is best used within four weeks or so.

Ordering enough KPV 4mg

Map out the doses per group, multiply by the number of days, and add a margin. It’s cheaper to order one extra vial at the start than to restart a study.

Where KPV fits

In short, KPV is a three-amino-acid alpha-MSH fragment studied for calming inflammation. Here’s how its neighbors differ:

• BPC-157 is the 15-amino-acid repair peptide with the largest body of rodent research
• TB-500 is the 43-amino-acid actin-binding protein, studied for cell movement and wound repair
• ARA-290 is an 11-amino-acid peptide from erythropoietin that protects tissue without raising red cells
• B7-33 is a relaxin-2 fragment studied for fibrosis
• GHK-Cu is the copper-binding tripeptide studied for collagen and skin repair

Each covers a different step of repair, from new blood vessels and cell movement to inflammation, fibrosis and matrix rebuilding. All of them are on our BPC-157 and recovery peptides page.
