We work with longstanding farmers with whom we've cultivated trusting relationships and who share our vision and high standards. To ensure quality we test each batch with our GCMS equipment but this information is currently held private, as it also includes some proprietary information on the reports. That said, we are working with a 3rd party to get verified results published for the general public. 100% purity is guaranteed.
