A Certificate of Analysis is a lab report for a specific production lot of a supplement. It records what the lab tested for, the method used, the acceptable limit, and the actual result. A COA lets you check for yourself that a batch met specifications for heavy metals, microbial contamination, and active-ingredient potency before it was released for sale.

Some are, and the table says which. Our electrolyte, creatine, and omega-3 lots were tested by Ethos Analytics in Phoenix, Arizona, an ISO/IEC 17025 accredited laboratory (Acc. #117798) that is independent of the manufacturer. Our joint support gummy lot was tested by Summit Nutritional Laboratories in Spanish Fork, Utah, also ISO/IEC 17025:2017 accredited (PJLA Acc. #75696). The remaining products are released on a certificate from the producing facility's own quality-control lab, which is not an independent third party. We label every row so you never have to guess which kind you are looking at.

The certificates on this page cover the four heavy metals of concern (arsenic, cadmium, lead, and mercury) by ICP-MS against USP <233> or USP <2232> limits, and microbial contamination (total plate count, yeast and mold, coliforms, E. coli, Salmonella, and Staphylococcus aureus) against USP <2021> and <2022> limits. Active-ingredient potency is listed only where that specific certificate includes the test, and the table names which ingredient was measured.

XGRITX products are produced by more than one manufacturing partner, and each partner uses its own testing arrangement. We publish the certificate we actually received for each lot rather than dressing it up. If a product's testing changes, this page changes with it.

The joint support gummy certificate covers a lot that has since passed its expiration date, and it verifies vitamin E potency rather than glucosamine. The High Octane certificate confirms the powder passed heavy-metal and microbial testing, but its label-claim panel was run on a different pre-workout formulation, so it is not potency verification for this product. We publish both because they are the documentation we hold and you are entitled to see it. When current-lot certificates are issued, this page will be updated.

No. These certificates verify contaminants and potency. They do not test for, and cannot guarantee, the outcome of any workplace or DOT drug screen. We choose ingredients with tested workers in mind, but if you are subject to testing, review the full ingredient panel on the label and check with your employer or medical review officer first.

The lot number and expiration date are printed on the bottom or side of the container. Match it to the Lot column in the table above. If your lot is not listed, email craig@xgritx.com with the product name and lot number and we will send you the certificate for that batch.
