Whichever seller you use, match the certificate to the lab's own records before trusting a vial: search its code in the Freedom Diagnostics lookup or check a Janoshik report with its key (how to verify a Janoshik report). A certificate covers one tested batch, so compare its batch number and date with the vial you receive.
