Certificate of Analysis (COA)

A COA is a verified document that provides details about the testing lab, the brand and product question, along with the potency of the ingredients the product contains. In the case of hemp, CBD and cannabis, the ingredients refer to cannabinoids like THC, CBD, CBG and CBN.
