Yes, absolutely! We always test the final products. In fact, all our suppliers are testing incoming raw materials and this is their standard procedure. Once the products are packed and ready to go we conduct lab test for each manufacturing lot - microbial and certain metals panel tests. Some of our products are also tested in US ISO certified lab, 3rd party lab not affiliated with our company. For our Siberian supplements, manufactured by Evalar and by Vitalabs we accept their in-house COA and test results. Please contact us if you have any questions: contact@siberiangreen.ca
