## Description

Each capsule delivers exactly 500 micrograms of the tripeptide Lys-Pro-Val (KPV), for oral studies; bottles hold 30 or 60. KPV corresponds to the last three amino acids of alpha-melanocyte-stimulating hormone. We make it by solid-phase synthesis, purify it by reversed-phase HPLC to ≥99% before the capsules are filled, and document each lot on a certificate that matches the number printed on your bottle.

An oral format has a clear rationale for this sequence. KPV research repeatedly reports uptake via PepT1, an oligopeptide transporter of the intestinal lining that is said to be upregulated in inflamed tissue. As the transporter is located exactly where KPV is most studied, delivering it orally in gut models is a deliberate design choice, not merely a convenient substitute.

With a mass of just 342 g/mol, KPV is also exceptionally small, so 500 micrograms represents many more moles than the same weight of a large peptide would. In the lab, capsules spare you from weighing out fractions of a milligram — where tiny absolute errors turn into large percentage ones. Supplied only as research material — not a food supplement and not a medicine.

## Frequently asked questions

### What amount of KPV does each capsule contain?

500 micrograms of the Lys-Pro-Val tripeptide, mixed with an inert filler so every capsule has a uniform fill weight. Bottles of 30 or 60 have a tamper-evident closure and contain a desiccant.

### Why offer KPV orally rather than in a vial?

Studies report that PepT1 — a transporter for small peptides found in the gut lining — takes KPV into cells, and that there is more of this transporter in inflamed tissue. As gut inflammation is KPV's main research field, giving it by mouth delivers it where the target tissue is.

### Isn't 500 micrograms rather little?

In weight, yes — but KPV weighs only 342 g/mol, so 500 micrograms contains far more molecules than 500 micrograms of a 30-residue peptide. Capsules also save you from weighing amounts below a milligram, where even small mistakes become large relative errors.

### How pure is the peptide, and is there a COA?

HPLC (reversed-phase) purification brings it to ≥99%, and its mass is checked before filling. The certificate carrying the lot number shown on your bottle can be requested at any time, whether before you buy or afterwards.

### How should the capsules be stored?

Keep the bottle closed, somewhere cool and dry and out of direct sunlight, leaving the desiccant inside. Peptide powder draws moisture from the air easily, so open the bottle as little as possible in humid conditions and never move the capsules into an unsealed container.
