The CoA for the specific batch you would receive is reviewed during your consultation and ships with the material.

The certificate names the laboratory that took the measurement, the date, the task number, the method and the purity found. PeptoClinic publishes the full reports uncropped, exactly as the laboratory printed them.
It is the report an analytical laboratory issues on a specific sample. Four things are worth checking: which compound it claims to have measured, by what method (HPLC for purity, mass spectrometry for identity), what figure it found, and whether the task number can be verified against the laboratory. A certificate with no verifiable task number is a picture.
