Every batch record and certificate on this prototype is an illustrative sample. Batch numbers, purity figures, and dates shown here are representative placeholders, not results from a shipped lot.
What every COA discloses
A purity number on its own means nothing. A real certificate names the method, the laboratory, and the batch it belongs to. Here is the layout of the report attached to every lot.
The lot printed on the vial must match the batch on the certificate exactly. A generic or missing batch number is a red flag.
A real COA names the independent lab that ran the test. Call or email them and confirm they issued that document.
Purity should be stated as a specific method such as reverse-phase HPLC, not an unqualified percentage.
The analysis date should be recent and tied to the lot you received, not a single certificate reused across batches.
