Our pharmaceutical grade THC Pure Co2 Extract is derived through a sub-critical CO2 process that is low temp stabilized to preserve the naturally occurring and essential terpenes of cannabis. This extract is then further refined using state of the art equipment and organic materials through proprietary practices. Our oils have zero hydrocarbons or additives such as propylene glycol, vegetable glycerin, or other thinners. We do not adulterate the oil by adding terpenes. The oil we produce only has the native terpenes from the processed cannabis.
