How to check a certificate
Check the report number above with the issuing laboratory, open the certificate in the COA library and match the batch or lot on the vial; after delivery, scan the item's PepCode to see its own record. A COA says nothing about sterility or endotoxins unless it tests for them (what a COA cannot tell you).
