KPV Peptide | 12mg | 3ml
KPV is a synthetic tripeptide composed of the amino acids lysine–proline–valine, corresponding to residues 11–13 of α‑melanocyte‑stimulating hormone (α‑MSH). It is widely used in research as the smallest functional fragment of α‑MSH capable of engaging melanocortin‑associated signalling pathways without requiring the full‑length hormone. In biochemical and cellular experimental systems, KPV is examined for its influence on melanocortin‑linked signalling networks and downstream intracellular processes involved in immune activity and inflammatory regulation. Research typically focuses on both receptor‑associated and receptor‑independent mechanisms, transcriptional responses, and peptide stability under controlled laboratory conditions. The molecular effects observed vary according to concentration, model type, and experimental design, positioning KPV as a tool for studying peptide‑driven signalling rather than for defining specific biological or physiological outcomes.

How we ship it
Every pre-mixed vial leaves the UK cold and arrives in a plain box. Refrigerate on arrival at 2–8 °C.

Chilled
Vials travel with frozen gel packs inside a sealed foil pouch, which holds temperature for roughly seven days in transit.

Insulated
The pouch sits inside a wool-lined envelope, so the cold chain survives a normal courier journey.

Discreet
Plain outer box with no branding and nothing on the label that names the contents.
Same-day dispatch
Order before 3pm GMT, Monday to Friday.
Free over £100
Tracked UK delivery, next working day.
2–8 °C on arrival
Refrigerate as soon as the parcel lands.
KPV: research FAQs
- What is KPV?
- KPV is a synthetic tripeptide composed of the amino acids lysine, proline and valine (Lys-Pro-Val). It corresponds to the C-terminal residues 11-13 of alpha-melanocyte-stimulating hormone (alpha-MSH) and is one of the smallest fragments derived from that sequence. In laboratory research it has been studied in connection with melanocortin-associated signalling pathways. It is supplied strictly as a reference compound for in-vitro laboratory research use only.
- What is KPV studied for in research?
- In biochemical and cellular experimental systems, KPV has been investigated for its influence on melanocortin-linked signalling networks and downstream intracellular processes relevant to immune activity and inflammatory regulation. Preclinical work typically examines both receptor-associated and receptor-independent mechanisms, transcriptional responses and peptide stability under controlled conditions. These are laboratory observations only; the molecular effects reported vary with concentration, model type and experimental design, and no human or physiological outcome is implied.
- Is KPV legal to buy in the UK?
- KPV is legal to buy and possess in the UK for laboratory research purposes. It is not a licensed medicine and cannot be sold for human or veterinary consumption. Every order is labelled and supplied for in-vitro research use only.
- What purity is your KPV, and is it lab-tested?
- Our KPV is verified to 99%+ purity by HPLC analysis. The figure printed on each batch's Certificate of Analysis is the actual value recorded in the laboratory for that batch, not a generic marketing claim. All material is synthesised and dispatched from our own UK facility.
- Does KPV come with a Certificate of Analysis?
- Yes. A batch-specific Certificate of Analysis (COA) ships with every order, documenting the identity and purity of the material you receive. Sample COAs can also be viewed in our COA library before you purchase, so you can review the documentation in advance.
- How is KPV supplied, stored and handled for research?
- KPV is supplied in a sealed vial and shipped cold-chain. Refrigerate at 2°C–8°C as indicated on the label, keep the vial sealed and away from light, and check the batch Certificate of Analysis supplied with your order for the recorded appearance and presentation. Handling should follow standard aseptic laboratory practice, consistent with its designation for in-vitro research use only.
