Defined Research tests every lot to ensure safety and quality standards are met. We use CBD isolate that is 99.9% pure to ensure each batch is exactly the same and has 0.0% THC. Our CBD isolate is from a GMP certified manufacturer using Colorado grown hemp.

Our third party testing is done at an ISO/IEC 17025:2005 accredited laboratory and recognized by the United States Food and Drug Administration (FDA) lab. All of our products are tested for Potency, Terpenes, Pesticides, Heavy Metals, Residual Solvents, Foreign Materials and Bacteria.

Nothing is sold unless it passes.
