Products, Testing & Quality
Yes, every batch is. Before a batch is approved for sale, a sample is sent to an independent analytical laboratory. Identity is confirmed by mass spectrometry (LC-MS), and purity is measured by high-performance liquid chromatography (HPLC). Only batches that meet our purity threshold are released, and we publish the Certificate of Analysis (COA) for that exact lot so you can verify the results yourself in our COA Library.
