Customers should want to see a Certificate of Analysis (COA) on the raw material they are purchasing for their end product. Our COAs are lot specific. For that reason, we do not “publish” our COAs. We take a composite sample from each lot and sub-lot and have it analyzed by a third party laboratory. When material meets our high standards we retain the sample and material and make the lot-specific Certificate of Analysis available to customers for perusal. If the material does not meet or exceed our expectations, we reject it. We ALWAYS strive to exceed our specification expectations. To request a copy of our Wheatgrass specification Sheet or a LOT SPECIFIC COA, email me at firstname.lastname@example.org.
