Get four 30 ml bottles for the price of three! Our Full Spectrum hemp oil is made from the whole plant, supercritical CO2 extracted, and each batch is third-party lab tested for purity. This ensures each bottle contains the proper amount of not only CBD, but all essential cannabinoids such as CBG, CBC, and CBN, as well as terpenes and less than .3% THC, a negligible amount. We also add CBD isolate for strength and efficacy. As always, we use only the finest quality, organic hemp from select Colorado farms.
