Verified — the lab's own database returned the same document, byte for byte.

Unverified — the lab couldn't find it, or something doesn't match.

Nothing on file — no document exists to check.

Numbers are per lot, from the lab's own copy of each certificate. They are not product claims. A lot you don't see here hasn't been checked — request it below.

How a row gets here

Someone requests a check, or we pull a lot from a vendor's product page.
We open the certificate and record the lab, search code, lot, dates, and every result.
We enter the search code at the lab's public lookup.
Found → we compare the two files. Identical = Verified. Not found or different = Unverified. No certificate at all = Nothing on file.
We check the listing against the lot and note any mismatch.
It goes in this table the same day, and to the weekly bulletin.

What this table does not tell you

Where the product was made. A lab report says what's in the vial, not where it came from.
Whether anything is safe or does anything in people. Nothing here is approved for human use.
Anything about a lot that isn't in the table.

Other vendors

Same checklist, same table. If you'd like a vendor added, send a product link. We publish failures for every vendor, including the one that pays us.
