Gold Standard Analytics is an independent laboratory. We report what we measure on the sample as received; we do not manufacture, sell, or endorse any product, and a certificate here is not a claim about anything beyond that sample. Customers may keep a certificate private — those stay verifiable by accession at COA lookup with the key printed on the document.
