Certificates of Analysis

Every product page already shows the Certificate of Analysis we receive directly from our supplier. This page is different: it's our own independent testing programme. We send samples of our products to Janoshik Analytical, an independent third-party lab, at our own cost — as an extra layer of verification beyond what our supplier provides. We're rolling this out one product at a time, so more certificates will be added here over time.
