We pay close attention to our ingredients and have our CBD oils tested regularly. The independent specialist laboratory of the Institute for Hemp Analysis (IFHA) confirms the active substance analysis of our contained cannabinoids. The CBD Oil 5% has a cannabinoid profile with an undetectable amount of THC (D9-tetrahydrocannabinol), the CBD Oil 10% has an amount of less than 0.03% THC (D9-tetrahydrocannabinol). In Germany, less than 0.2% THC (D9-tetrahydrocannabinol) is mandatory, thus the HempCrew CBD oils are significantly below this level.
