How to Read a KPV Certificate of Analysis (COA)
A Certificate of Analysis is only useful if you know which number on it matters for the compound in front of you. For KPV, the informative checks are not the same as for a generic short peptide.
Overview
Check the weight near 342. Because it is so small, the salt makes up more of the vial weight, so use the peptide-content figure if the report gives one.
What KPV actually is
A three-part peptide taken from the tail of the natural hormone alpha-MSH. It keeps the calm-inflammation side of that hormone without the tanning side, and is studied around gut and skin inflammation.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Assays that are informative for KPV
What to check on the COA
Confirm the mass near 342.4 Da. At this small size, net peptide content versus salt weight is worth checking, since the counterion is a larger fraction of the vial mass than for longer peptides.
Truncated di-peptide sequences and free amino acids from synthesis.
Verify a Popular Peptides batch
Every batch is third-party tested by HPLC and LC-MS with a published Certificate of Analysis (≥99% purity). Enter a lot number to pull the COA for the exact vial in front of you.
What KPV is studied for
Studied for modulation of inflammatory pathways such as NF-kB in cell and tissue models, inherited from the alpha-MSH parent.
A significant share of the literature examines gut-inflammation research models.
Investigated in dermal and tissue-repair contexts without the pigmentation activity of the full hormone.
Summarizes published preclinical literature. Provided for research reference only; not a claim of efficacy or a description of human use.
