How to verify KPV is authentic

Step-by-step guide to verifying your KPV is genuine: checking the COA, matching the batch number, and downloading from the product page.

Step 1: Locate the batch number

Every Peptify KPV vial has a batch (lot) number printed on the label. Note this number down — it should match the Certificate of Analysis published on the product page for that specific batch.

Step 2: Download the COA from the product page

The batch-specific COA for your KPV is downloadable directly from the product page on peptifyuk.com. This is the most reliable verification method because the document is hosted under our control, tied to the batch number, and includes the original HPLC chromatogram image plus mass spectrometry data.

If a supplier does not publish batch-specific COAs or only provides a generic purity claim, that is a significant red flag.

Step 3: Check the HPLC peak

On the COA, look at the HPLC chromatogram. A genuine KPV sample should show a single dominant peak at the expected retention time, with purity >99% (peak area). The mass spectrometry section should confirm the molecular weight matches the theoretical mass of KPV.

Any chromatogram with multiple large peaks, or where the purity percentage looks inconsistent with the visible peak, should prompt you to contact the supplier for clarification.

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.
