Match the sample
Check the product, lot where known, sample date, laboratory, method, and report identifier. Confirm how the sample was selected and purchased. A vendor-selected vial and an independent website purchase are different evidence.
Keep analytical attributes separate
Identity and analytical purity do not establish heavy-metal levels, residual solvents, sterility, endotoxins, labeled quantity, or safety. The routine testing panel does not assess those attributes.
Read findings and corrections together
A completed report may contain concerning or inconclusive findings. Read uncertainty, follow-up review, and published corrections alongside the original result. Public redactions must be identified; private supplier evidence is not part of the public report.
