How to store KPV
Practical storage protocol for KPV: temperature, light, reconstitution timing, and shelf life in a research setting.
Lyophilised (freeze-dried) storage
Unreconstituted KPV, like most research peptides, is stable when stored in its original sealed vial at -20°C for long-term storage. For short-term use (under 3 months), refrigeration at 2-8°C is acceptable. The vial must be protected from direct light and moisture.
Peptify dispatches KPV in temperature-tolerant packaging from the UK, usually arriving within 24-48 hours of dispatch.
After reconstitution
Once KPV is reconstituted with bacteriostatic water (BAC water, 0.9% benzyl alcohol), the solution should be stored at 2-8°C (refrigerated) and used within 28 days. Bacteriostatic water's preservative system inhibits microbial growth for roughly four weeks after first puncture — significantly longer than sterile water, which must be used immediately.
Avoid freeze-thaw cycles. Never leave the vial at room temperature for extended periods, and keep it in its original rubber-stoppered vial to minimise contamination risk.
Shelf life and quality verification
Peptify publishes a batch-specific expiry date on every KPV COA, alongside HPLC chromatogram data and mass spectrometry confirmation. The full Certificate of Analysis for your specific batch is downloadable from the product page.

Frequently asked questions
What is KPV researched for?
KPV is primarily studied for its anti-inflammatory effects, particularly in gut health research. It suppresses NF-kB and reduces pro-inflammatory cytokines.
How does KPV relate to alpha-MSH?
KPV is the C-terminal tripeptide fragment (Lys-Pro-Val) of alpha-melanocyte-stimulating hormone. Research has examined whether the tripeptide retains the anti-inflammatory signalling of the parent molecule.
What purity does Peptify supply?
Peptify KPV is 99%+ HPLC-verified. Every batch ships with a downloadable Janoshik Analytical Certificate of Analysis matching the lot number printed on the vial.
