This page lists every third-party certificate of analysis (COA) we hold for the catalogue, by compound and by batch. Nothing is summarised. The lab, the result, the batch or lot number and the date appear as issued.
If a compound is not on this page, we do not yet have an independent result for it and its product card says "Batch COA on request".
Enter the task number and the key shown in the row.
The lab's own copy of the report loads. If it does not, the result is not genuine, and we want to know.

What the labs measure: purity by HPLC (how much of the vial is the named peptide), identity by mass spectrometry (that it is the right molecule), and for blends the measured content of each peptide. These are analytical results on research material. They are not a claim about safety or suitability for any use.
