Yes, every batch is. Before a batch is approved for sale, samples are sent to an independent analytical laboratory in the United States.

Only batches meeting our purity threshold are released, and we publish the certificate of analysis (COA) for that batch so you can verify the results yourself in our COA Library or by browsing all published laboratory results.
