What is KPV?
KPV is the tripeptide Lys-Pro-Val, the C-terminal fragment of alpha-melanocyte-stimulating hormone (alpha-MSH). It carries the molecular formula C16H30N4O4 and a molecular weight of 342.43 g/mol, identified by CAS number 67727-97-3 and PubChem CID 125672. Kovalabs supplies it as a lyophilised solid for laboratory research only.
As a short, defined-sequence peptide, KPV is studied as a reference fragment of the larger alpha-MSH molecule. It is one of several research peptides listed in our research category, supplied strictly as a non-clinical reference compound and not for human or veterinary use.
Is KPV legal in the UK?
KPV is not a controlled drug under the Misuse of Drugs Act 1971 and is legal to buy and possess 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. The purchaser is responsible for handling, storing and using the material in compliance with applicable laws and institutional rules. See our research disclaimer for full terms.
How is identity and quality assured?
Every batch of KPV is released only after independent identity and purity testing. Purity is assessed at 99% or greater by HPLC, and identity is confirmed against the expected mass and sequence Lys-Pro-Val. The verified identifiers are CAS 67727-97-3, PubChem CID 125672, InChIKey YSPZCHGIWAQVKQ-AVGNSLFASA-N, formula C16H30N4O4 and molecular weight 342.43 g/mol. A Certificate of Analysis accompanies each batch, so not all material sold as KPV is equivalent: check the CoA. View our Certificates of Analysis for current batch documentation.
What does the research on KPV investigate?
The published literature investigates KPV as a fragment of alpha-MSH within melanocortin signalling and inflammatory-pathway model systems, using in-vitro and animal models. This is pre-clinical, mechanistic research only. None of it establishes a benefit, effect or outcome in humans, and KPV is not a licensed medicine. For a referenced overview of the research area, read our KPV peptide research monograph; the product page is for identity, supply and quality information only.
Synthesis and supply
KPV is manufactured to research grade by solid-phase peptide synthesis and supplied as a white to off-white lyophilised powder. For laboratory work it is typically reconstituted with a compatible solvent such as bacteriostatic water. Store the lyophilised solid at -20C, kept dry and protected from light; hold reconstituted material at 2-8C. Researchers comparing short peptides often also reference BPC-157, GHK-Cu and TB-500, all stocked as distinct research compounds with their own CoAs.

- What is KPV peptide?
- 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. Kovalabs supplies KPV as a lyophilised powder for laboratory research use only, not for human or veterinary use.
- Is KPV legal in the UK?
- 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.
- Is KPV for human 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 Kovalabs.
- Has KPV been shown to be safe or effective in humans?
- No. The available literature on KPV is pre-clinical and mechanistic, conducted in in-vitro and animal model systems within melanocortin and inflammatory-pathway research. None of it establishes safety, efficacy, a benefit or any outcome in humans. KPV is not a licensed medicine and Kovalabs makes no human-use claims of any kind.
- What does the research on KPV investigate?
- 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.
- Is all KPV the same?
- No. Material sold as KPV can vary in purity and identity between suppliers. Kovalabs 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.
- What are the molecular identifiers for KPV?
- 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.
- How is KPV supplied and reconstituted?
- 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.
- How should KPV be stored?
- 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.
- Does KPV come with a Certificate of Analysis?
- 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.
- How does KPV relate to alpha-MSH?
- 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 Kovalabs as a research reference compound only, not for any human or veterinary use.
- How does KPV differ from GHK-Cu?
- 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 Kovalabs strictly as research reference compounds, not for human use.
- Where can I buy KPV in the UK?
- KPV is available to buy from Kovalabs 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.
- Is KPV a peptide?
- 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. Kovalabs supplies it as a lyophilised peptide for laboratory research use only, accompanied by a Certificate of Analysis.
