Vendor-Verification Methodology

Checks performed

• Resolve the vendor and product destination.
• Record the last check independently from the editorial review date.
• Distinguish vendor-supplied COA and testing claims from independently documented laboratory results.
• Display price, currency, amount, stock, batch and laboratory only when those data are actually available.
• Check commercial links for sponsored, nofollow and noopener attributes.

What verification does not mean

A vendor listing is not medical endorsement, a guarantee of product identity or sterility, a statement of universal legality, or a recommendation that anyone purchase or use a substance.

Scoring independence

Vendor verification has no effect on evidence grade, safety assessment, human-evidence summary, regulatory status or reviewer attribution.
