Tell us which product you are evaluating and we will send the Certificate of Analysis for the batch currently in stock. A certificate covers one production batch, so the document you receive is the one that applies to the vial you would be shipped.
The certificate names the compound, the batch or lot reference, the vial fill weight, the identity and purity methods used, the laboratory that ran them and the date of analysis. If you have not read one before, our field guide walks through every line.

A purity figure applies only to the batch it was measured on, never to a product line. Certificates are provided for research-evaluation purposes only and do not constitute usage, dosage or safety-of-use guidance.
