Substantiation means backing up a claim with solid evidence. In this context, two essential parts must be addressed: what the product actually is (the MEAT) and that its integrity is preserved against interference (the TAMPER aspect). Verifying the material confirms you’re talking about the right substance, while ensuring tamper-evidence confirms the product hasn’t been altered after packaging or during handling. When both aspects are shown together, the claim is fully supported and credible. If you only prove one side—either the product’s identity or its tamper status—you leave room for error or fraud, so including both MEAT and TAMPER gives the strongest substantiation.
