Every production batch we sell is tested by an independent laboratory for identity and purity (99%+ by HPLC). The result is documented in a batch-specific Certificate of Analysis (COA).
With your order. A copy of the COA for your batch is included with every order, so you can match the batch number on your vial to the report.
Request a COA. Want the report for a specific batch before or after ordering? Email us with the product name and the batch number printed on the vial, and we will send the PDF.
