Full shipping informationKPV is a naturally occurring tripeptide (Lys-Pro-Val) derived from the C-terminal end of alpha-melanocyte-stimulating hormone (alpha-MSH). It has been studied for its immunomodulatory signaling in gastrointestinal and immune biology research models.

Description
KPV (Lys-Pro-Val) is a tripeptide made up of the amino acids lysine, proline and valine. Its sequence matches the last three residues (positions 11-13) of alpha-melanocyte-stimulating hormone (alpha-MSH), a 13-amino-acid peptide cleaved from the precursor protein proopiomelanocortin (POMC).
In published laboratory research, KPV has been examined in cell-culture studies of intracellular signalling in human keratinocytes and in cells expressing the melanocortin-1 receptor (MC1R), of the NF-kB pathway in intestinal epithelial cell lines, and of its uptake by the peptide transporter PepT1.

| Compound | KPV (Lys-Pro-Val, alpha-MSH C-terminal tripeptide) |
| Purity | ≥98% (class-level specification) |
| Format | Lyophilized powder |
| Reconstitution | Sterile water or saline |
| Storage | -20°C; 2-8°C after reconstitution |
Storage
Store at -20°C before reconstitution. Refrigerate at 2-8°C after reconstitution and use within 28 days. KPV is a small, stable tripeptide with good shelf life under proper storage conditions.
Where does the KPV sequence come from?
Alpha-MSH has the sequence Ser-Tyr-Ser-Met-Glu-His-Phe-Arg-Trp-Gly-Lys-Pro-Val, and KPV corresponds to its last three amino acids. Alpha-MSH is one of several peptides cleaved from proopiomelanocortin (POMC), the same precursor protein that gives rise to adrenocorticotropic hormone (ACTH).
In what kind of research is KPV studied?
The published studies summarised on this page are laboratory research: cell-culture work on melanocortin receptor signalling, on the NF-kB pathway and on peptide transport by PepT1. Their results describe observations made under experimental conditions only.
How does KPV differ from full-length alpha-MSH?
Alpha-MSH has 13 amino acids, while KPV consists of only its last three, so KPV is a much smaller molecule. Full-length alpha-MSH binds several melanocortin receptors (MC1R, MC3R, MC4R and MC5R). KPV is studied as a research compound in its own right.
KPV is supplied for research purposes only. Not for human use. Handle in compliance with institutional biosafety guidelines.

Why researchers choose CertaPeptides
Who actually tests this?
Selected lots are independently verified by Janoshik Analytical (Czech Republic) and published on the Janoshik public portal. Other lots ship with the supplier's batch specification. See /coa for the published wall.
View COAs →What if I get the wrong batch?
Every vial label carries a code. Look it up on our Verify page: it shows what CertaPeptides publishes for that code and, for a withdrawn lot, that the lot was withdrawn and why. If yours is withdrawn, or if the code on your label finds nothing, email us that code.
View COAs →Where does it ship from?
Romania (EU). We are CERTALAB SRL, CUI 54169956, VAT-registered. Sameday for Romania, GLS for most EU destinations, TCE Worldwide for the remaining cross-border EU and non-EU markets (UK, Switzerland). Delivery 1–15 business days depending on destination — exact window shown at checkout.
Shipping details →What if there's a problem?
You have a 14-day withdrawal right under OUG 34/2014 (Romanian/EU consumer law), with escalation to ANPC and alternative dispute resolution (SAL) available. Contact us at support@chinapeptideshop.com.
Returns policy →Product Information
This product is intended for scientific research and development purposes only. It is a chemical substance that shall not be used as a drug, medicine, active substance, or ingredient in any product intended for human or animal consumption. Researchers must handle this compound in accordance with their institutional biosafety guidelines. Use only in properly equipped laboratory settings with appropriate personal protective equipment.
Peptides in lyophilized (freeze-dried) form are shipped in sealed glass vials using standard delivery methods and do not require refrigeration during transit. Lyophilized peptides are highly stable at ambient temperatures for the duration of standard shipping (typical transit windows are shown at checkout). Once received, transfer the product to refrigerated storage (2–8°C) promptly.
Frequently Asked
Research peptides are supplied in lyophilized (freeze-dried) form. The amount of material is typically only a few milligrams — appearing as a very thin film or small pellet at the bottom of the vial, often nearly invisible. This is completely normal.
Unlike some suppliers who add bulk fillers (such as Mannitol), CertaPeptides provides pure peptide without unnecessary additives.
