KPV (Research Grade)

KPV is the C-terminal tripeptide fragment (Lys-Pro-Val) of alpha-MSH. It retains the anti-inflammatory signaling of the parent hormone without melanocortin receptor pigmentation activity, making it a clean tool compound in gut and skin inflammation research.

KPV specifications

Reference data researchers look up before ordering kpv. Every lot ships with documentation matching the batch number printed on the vial.

  • Class: alpha-MSH C-terminal fragment
  • Sequence: Lys-Pro-Val
  • No pigmentation receptor activity
  • Storage: -20°C lyophilized

KPV purity testing and certificate of analysis

Each kpv lot is released only after an independent purity panel. HPLC quantifies purity, LC-MS confirms molecular identity, and the lot-matched certificate is published so the number on your vial matches the report you download.

  • ≥99% HPLC purity specification
  • LC-MS mass confirmation on every batch
  • Endotoxin and sterility panel documentation
  • Lot-matched kpv COA published on the certifications page

KPV reconstitution and BAC water ratios

KPV ships lyophilized. Reconstitute with bacteriostatic water containing 0.9% benzyl alcohol. The ratios below assume a standard U-100 insulin syringe.

  • 10mg vial + 2mL BAC water = 5mg per mL (10 units = 500mcg)
  • 10mg vial + 5mL BAC water = 2mg per mL (25 units = 500mcg)
  • Also studied in oral and topical preparations
  • Refrigerate reconstituted vials

Where to buy kpv

PX1 Research synthesizes and fills kpv in a US cGMP-compliant facility rather than reselling imported material, so purity documentation traces back to the production lot. Multi-vial pricing steps down at 3, 5 and 10 vials, and subscription intervals are available on the product page.

Frequently asked questions

What is KPV derived from?

It is the final three residues of alpha-melanocyte stimulating hormone, which carry the anti-inflammatory portion of the sequence.

Does KPV cause tanning like melanotan?

No. KPV lacks the melanocortin-1 receptor binding region responsible for pigmentation.

Is a certificate of analysis provided with kpv?

Yes. Every kpv lot has a published, lot-matched COA showing HPLC purity and LC-MS identity confirmation.

How should kpv be stored?

Store the lyophilized vial at -20°C protected from light. Once reconstituted with bacteriostatic water, keep it refrigerated at 2–8°C.
