KPV is a synthetic tripeptide (lysine-proline-valine), a C-terminal fragment of alpha-MSH, studied in research into inflammatory-pathway and melanocortin signalling in experimental models.
KPV is the tripeptide Lys-Pro-Val, the C-terminal fragment of alpha-melanocyte-stimulating hormone (alpha-MSH). It has the molecular formula C16H30N4O4, a molecular weight of 342.43 g/mol, and CAS number 67727-97-3. Kyrolabs supplies KPV as a lyophilised powder for laboratory research use only, not for human or veterinary use.
Yes. KPV is not a controlled drug under the Misuse of Drugs Act 1971 and may lawfully be bought and possessed in the UK as a laboratory reference material. It is supplied for research use only and is not authorised as a medicine by the MHRA. It is not for human or veterinary consumption, and the purchaser is responsible for lawful and appropriate handling and use.
No. KPV is supplied strictly as a reference compound for non-clinical laboratory research. It is not a medicine, supplement or cosmetic, and it is not intended or supplied for human or veterinary use. No human, cosmetic or veterinary application is intended or implied by Kyrolabs.
Published research investigates KPV as a fragment of alpha-MSH in melanocortin signalling and inflammatory-pathway model systems, using laboratory and animal models. These are research-context findings only and are not evidence of any effect in humans. A referenced overview is available in our KPV peptide research monograph; the product page covers identity, supply and quality only.
No. Material sold as KPV can vary in purity and identity between suppliers. Kyrolabs releases every batch only after independent testing, with purity assessed at 99% or greater by HPLC and identity confirmed against the expected mass and the sequence Lys-Pro-Val. A Certificate of Analysis accompanies each batch, so always check the CoA rather than assuming equivalence.
KPV has the sequence Lys-Pro-Val, molecular formula C16H30N4O4 and molecular weight 342.43 g/mol. Its CAS number is 67727-97-3, its PubChem CID is 125672, and its InChIKey is YSPZCHGIWAQVKQ-AVGNSLFASA-N. It is also referred to as alpha-MSH (11-13). These identifiers are stated on the accompanying Certificate of Analysis.
KPV is supplied as a white to off-white lyophilised powder. For laboratory work it is typically reconstituted with a compatible solvent such as bacteriostatic water to prepare a stock solution for research procedures. Reconstitution volumes are chosen by the researcher according to the experimental protocol. KPV is for laboratory research use only.
Store the lyophilised KPV solid at -20C, kept dry and protected from light. Once reconstituted, hold the solution at 2-8C and use it within the timeframe appropriate to your protocol. Proper cold, dry, light-protected storage helps preserve peptide integrity for laboratory research.
Yes. Every batch of KPV is released with a Certificate of Analysis documenting purity by HPLC (99% or greater) and identity confirmed against the expected mass and sequence. You can view current batch documentation on our Certificates of Analysis page. The CoA is the reference for confirming what you have received.
KPV is the C-terminal tripeptide fragment of alpha-melanocyte-stimulating hormone (alpha-MSH), corresponding to residues 11 to 13 (Lys-Pro-Val). It is therefore studied as a defined fragment of the larger alpha-MSH molecule. KPV is supplied by Kyrolabs as a research reference compound only, not for any human or veterinary use.
KPV and GHK-Cu are distinct molecules. KPV is the tripeptide Lys-Pro-Val (CAS 67727-97-3), a fragment of alpha-MSH. GHK-Cu is a copper-binding tripeptide (Gly-His-Lys) supplied as a separate product. They have different sequences, identifiers and CoAs. Both are sold by Kyrolabs strictly as research reference compounds, not for human use.
KPV is available to buy from Kyrolabs for despatch within the UK, supplied as a CoA-verified lyophilised powder at 99% or greater HPLC purity. It is sold strictly for laboratory research use only and is not for human or veterinary consumption. See the research disclaimer for the full terms of supply.
Yes. KPV is a tripeptide, meaning a peptide made of three amino acid residues: lysine, proline and valine (Lys-Pro-Val). It is the C-terminal fragment of alpha-MSH. Kyrolabs supplies it as a lyophilised peptide for laboratory research use only, accompanied by a Certificate of Analysis.
