COA Test Reports Scored

A COA is a laboratory document describing what a specific batch of material was found to contain, typically covering identity and purity, and sometimes heavy metals, endotoxins or sterility. It should name the product, the batch or lot, the analytical method used and the laboratory that ran it.

No. Every certificate listed here was produced by or for the supplier. We link to the supplier's own document rather than rehosting it, so you always read the original. We do not operate a laboratory and do not commission testing.

Independent third-party testing rather than in-house QA; a lot number matching the vial; a named method such as HPLC-UV or LC-MS with real parameters; an actual chromatogram or spectrum rather than only a summary figure; and a recent date with an identifiable analyst or lab.

Because the vendor has not published one we can open, or the link they published does not resolve to a certificate. We show "Report Pending" rather than implying a document exists. An absent COA is information worth weighing.

No. A certificate describes one batch at one point in time and cannot speak for a vial from a later production run. Documents can also be reused across batches or edited. Treat a COA as one input among several rather than proof.
