What is — KPV
KPV is a synthetic tripeptide (lysine-proline-valine) corresponding to the C-terminal fragment of the alpha-melanocyte-stimulating hormone (α-MSH). Peptworks supplies it as a lyophilised 10 mg vial at >=98% HPLC purity. It is a research-use-only (RUO) laboratory reagent — not a medicine, supplement, cosmetic or medical device, and not for human or animal consumption. Stock ships from inside the EU for intra-community delivery in 3-5 business days, available as bulk unbranded vials (white-label).
As the C-terminal tripeptide of α-MSH, KPV is studied within the melanocortin signalling area. In preclinical and in-vitro models, research has focused on its interaction with intracellular inflammatory signalling pathways, including reported modulation of NF-κB-associated transcriptional activity and pro-inflammatory cytokine expression in cultured cells. Peptworks describes these mechanisms strictly as research-model observations; no therapeutic mechanism in humans is claimed or implied.
Research
- Melanocortin pathway and α-MSH fragment signalling (in vitro)
- NF-κB and intracellular inflammatory pathway modulation in cell cultures
- Epithelial and intestinal barrier research models
- Wound-healing and tissue-repair assays (preclinical)
- Pro-inflammatory cytokine expression studies
- Peptide stability, reconstitution and formulation R&D
Advantages
- In cell-culture models, studied for modulation of pro-inflammatory signalling
- Investigated in preclinical tissue-repair and epithelial-barrier models
- Used as a reference α-MSH C-terminal fragment in melanocortin pathway screening
- >=98% HPLC purity supports reproducible in-vitro experimental data
- Lyophilised 10 mg format allows flexible reconstitution for varied laboratory protocols
Safety
- As an RUO reagent, no human or clinical safety profile has been established
- Preclinical literature generally reports KPV as low-toxicity in the models studied, though available data are limited
- Handle as a laboratory chemical: use appropriate PPE and follow local lab safety and disposal protocols
- Reconstituted peptide stability is limited; store and handle according to laboratory best practice
Ideal for
- In-vitro inflammation and cytokine-expression assays
- Melanocortin / α-MSH pathway research programmes
- Epithelial and gut-barrier model studies
- Comparative peptide screening and reference standards
- Formulation, reconstitution and stability R&D
- White-label catalogue expansion for B2B research suppliers

Frequently asked questions
Where can I buy KPV in bulk in the EU?
Peptworks supplies KPV (10 mg lyophilised vial) wholesale to B2B buyers from stock already inside the EU. Orders ship intra-community in 3-5 business days with no customs clearance. You can order bulk unbranded vials (white-label). Orders start from a 4-vial pack per reference.
What is the wholesale KPV price per vial?
KPV 10mg has two public per-vial prices: €39.90 in a 4-vial pack and €25.00 from 10 vials of this reference (box price). There are no volume tiers. Shipping is free on orders from €500 (€24.90 below), inside the EU with no customs. Payment is in crypto: USDC or USDT (Polygon or Base) or Bitcoin — paying in crypto is what keeps our prices this tight, with no card or bank fees.
Do you offer KPV as white-label?
Yes, in the white-label sense: KPV comes in unbranded vials, with no brand on the vial, so you can resell it under your own label. Peptworks does not print or apply labels. Every batch is tested by an independent lab and ships from EU stock with no customs.
What is the minimum order for KPV?
The minimum is a 4-vial pack per reference; from 10 vials of a reference the lower box price applies. Vials ship in boxes of 10. There are no volume tiers, and orders from €500 ship free.
How is the KPV Certificate of Analysis verified?
Every batch ships with an independent Certificate of Analysis covering HPLC purity (>=98%) and heavy-metals testing. Each box carries a unique QR code that links to that specific batch's CoA, verifiable through Peptworks, so you and your customers can confirm authenticity and purity per batch.
Is KPV intended for human use?
No. KPV is a research-use-only (RUO) laboratory reagent for preclinical and in-vitro research. It is not a medicine, supplement, cosmetic or medical device, and it is not for human or animal consumption. Peptworks sells B2B to resellers and laboratories only, not to end consumers.
