Manufacturer statement
Nature's Bounty says: "Every Nature’s Bounty® product is subjected to numerous quality tests and assays throughout the manufacturing process to verify purity and full potency. As an added measure of quality assurance, the initial ingredients, as well as the final product are tested in our microbiological laboratory to make certain that the product is pure and free of harmful bacteria." The same page also says its facilities were audited by USP and STR, but I did not find an independently verifiable registry or product-specific certificate for this biotin product.

Manufacturer statement
Amazon listing image/text shows “Non-GMO Verified,” “Vegan Certified,” and “Third Party Tested”; NSF registry independently confirms a Sports Research product listing with NSF Certified for Sport® (though for Creatine Monohydrate Unflavored, not this biotin product). For this biotin product specifically, Sports Research’s own product page says “Third Party Tested Certified” and shows an NSF logo, but I did not find an NSF registry page for this exact biotin item.
