Before our mushrooms leave the lab where they undergo extraction, they’re tested for quality, purity and potency. This includes physical characteristics, chemical characteristics (including polysaccharide content), and microbiological characteristics. The results of this testing are documented in a Certificate of Analysis, which you can request from us at any time by contacting help@harmonicarts.ca. We also cyclically contract 3rd party testing at Canadian labs to further verify and validate the results of the Certificates of Analysis.
