Certificate verification

Is this CoA real?

Enter the certificate number and access key printed on any peptester Certificate of Analysis. We'll check them against our register and show you exactly what was issued.

How verification works

Three checks, no account needed.

Find the number

Every peptester certificate carries a number in the header and an eight-character access key in the band beneath it.

Check the register

We look both up against the certificates we have actually issued. Nothing else will match.

Compare the results

The register shows the compound, panel and measured results. If they differ from the document you were shown, the document has been altered.
