Every Batch Independently Tested

Before any batch goes on sale, a sample is sent to Janoshik Analytical, an independent lab, to check what it is, how pure it is and how much is in each vial. Every product links to the certificate for the batch we are sending out, and the batch number on that certificate matches the label on your order.
