A CBD Certificate of Analysis is a laboratory test result that includes product ingredients, batch number, testing date, and potency demonstrated by the percentage of cannabinoids and terpenes present in the batch. Each batch of ALL G product is tested by an independent laboratory that produces a Certificate of Analysis or COA to ensure authenticity and so you can see what’s in your product, how potent your product is, AND importantly, what’s not in your product – like contaminants and fillers.
