A Certificate of Analysis (C of A) is a document which states every active and inactive substance used to manufacture a product. A C of A also shows that there are no additional ingredients added to the formulation. In order to assure the safety and efficacy of First Endurance products each lot is analyzed with a Certificate of Analysis. Every bottle sold will have a lot code printed on the bottle. The C of A for that lot code can be found below.
