KPV research overview
KPV is a tripeptide composed of lysine, proline, and valine, corresponding to the C-terminal fragment of alpha-melanocyte-stimulating hormone (α-MSH). Its three-residue length makes it one of the smallest peptides in the TrueBond Labs catalog. The product is presented as 10mg of lyophilized powder in a 3 mL vial, and lot TB-KPV-001 carries independent HPLC purity and mass-spectrometry identity verification completed before the material reached inventory.
As a fragment of α-MSH, KPV has been studied in preclinical research examining inflammation-related signaling pathways, epithelial cell models, and melanocortin-system biology. Its small size has additionally drawn interest in peptide-transport and structure-activity investigations. TrueBond Labs relays these research areas for informational context alone — no result, benefit, or application is asserted — and supplies KPV exclusively to qualified professionals conducting in-vitro laboratory work.
Anyone planning to buy KPV can examine the current third-party COA at /lab-reports, confirming HPLC purity at the ≥99% release threshold along with MS identity data. Handling follows the standard vial protocol: lyophilized storage at −20°C for 24+ months, then 2–8°C refrigeration for approximately 30 days once reconstituted. On the current certificate, lot TB-KPV-001 shows 99.6% purity for its 10.08 mg net fill.

KPV — frequently asked questions
What is KPV?+
KPV is a three-amino-acid peptide — lysine, proline, valine — that forms the C-terminal fragment of alpha-melanocyte-stimulating hormone. It has appeared in preclinical studies of inflammation-related pathways and melanocortin biology. TrueBond Labs supplies KPV strictly as a laboratory research compound; it is not intended for human or animal use and no administration information is provided.
What size KPV vial is available and what does it cost?+
KPV is stocked as a single 10mg lyophilized vial (SKU TB-KPV-10) priced at $37.99, packaged in the 3 mL format. Standard bundle pricing reduces the per-vial cost by 3% on two vials and 5% on three, and the free UPS 3-Day Select threshold of $250 applies across the whole cart.
Is KPV independently tested for purity?+
It is — the active KPV lot undergoes HPLC purity analysis and mass-spectrometry identity confirmation at an independent third-party laboratory, and only material verified at ≥99% purity is cleared for sale. The certificate is viewable at /lab-reports before you order, and the printed lot code identifies that same lot document.
How long does KPV last in storage?+
Sealed lyophilized KPV is rated for 24+ months when held at −20°C. Once your laboratory reconstitutes it, the solution should move to 2–8°C and be used within about 30 days. As with other peptides in the catalog, keep it away from light and do not subject the solution to repeated freeze/thaw cycles.
