“Party”
Evidence →No named laboratory or lot-specific certificate was found for this exact product. A related brand page names no testing issuer and links no product-bound report; its UPC is not published. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.
“in”
Evidence →“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
We looked and found no public proof. That does not count against the product.
