Certificates of Analysis.
Quick summary
Every batch currently in circulation is listed below with its independent HPLC and mass-spectrometry report. Cross-check any certificate directly at the issuing laboratory using the task number and unique key printed on the PDF.
Each certificate listed here belongs to a lot we are actively dispatching to UK researchers. As stock turns over, the replacement batch is re-tested and this table refreshes — so you only ever see paperwork that matches inventory on our shelves, never an archived or out-of-date report.
Use the table below to find a batch by product or test date. Every entry can be independently cross-checked at the issuing laboratory using the task number and unique key printed on the certificate.
All reports are issued by independent third-party laboratories. Each one can be re-checked directly with the lab using the unique key printed on the certificate.
