What this can and can't do

This is a strong filter, not a guarantee. We verify what the listing states and its review record supports — we don't physically test the product. A seller who misrepresents every field and buys enough reviews could, in principle, slip through; the reputation floor and full-text parse make that expensive, not impossible. For supplements especially, a mention of a certificate of analysis is not the certificate itself — for anything you'll ingest, ask the seller for the actual third-party lab report before you rely on it.
