How to read a COA

Five things to check

A real COA is tied to a specific production lot — the lot on the document should match the lot on your vial. A generic, reused certificate is a red flag.

Confirms the molecular weight matches the target compound. It answers the most basic question: is this actually the peptide on the label?

Reports the target peptide as a percentage of the sample — backed by an actual chromatogram, not just a number typed on a page.

One clean, dominant peak indicates high purity; a cluster of smaller peaks indicates impurities. We publish the graph so you can see it.

Recent testing by a named, independent lab carries far more weight than an undated certificate with no source.
