Verify a Certificate
Scan the code on your vial, or enter a lot number, and read that batch’s certificate where the laboratory published it — on its own website, not ours.
A lot is one production run. Every vial filled from that run is covered by the same set of test results. Scanning the QR code on the vial brings you straight to that lot’s record — this page is for when you have the number instead of the vial.
What happens when you search
One of two things. If the lot exists, you get a single result: a link to that lot’s certificate of analysis, or COA — the laboratory’s report of everything it measured in the batch. Open it. Then do the one check this page exists to teach: look at the address bar. The certificate lives on the independent laboratory’s own domain, not on ours. A document we hosted, we could quietly edit; a document another organization publishes on its own website, we cannot touch. The address bar tells you whose word you are taking. Here, it is the laboratory’s.
No lot substitution
The lookup returns the certificate for the exact lot you entered, or it returns nothing at all. It will never show you a different lot’s paperwork, because a certificate speaks only for the batch the laboratory actually tested — not for any vial that merely resembles it.
If a lot returns nothing
Re-check the number against the vial first; a single misread character is the usual cause. If it still returns nothing, contact support and include the lot number exactly as it appears. Every lot we release has a published certificate, so a genuine number with no record is something we want to hear about, and we will trace it.
Verifying a certificate from any supplier
Nothing above is a trick only we can perform. Wherever you buy, the same checks work. The certificate should name the exact lot in your hand. You should be able to reach it through the laboratory, not only through the supplier who benefits from it. And it should report identity — is it the molecule on the label — and content, how many milligrams are actually in the vial, not just purity, which is how much of the vial is one substance. If a supplier offers a “representative” certificate, one lot’s paperwork standing in for another’s, it tells you nothing about your vial. Our guide to reading a certificate walks through a real one line by line, and it works on any supplier’s paperwork, including ours.
The standard behind every certificate
A certificate tells you what the laboratory measured. The Testing Standard tells you what each number had to be: a numeric specification for every attribute, published before the lot existed, so the target can never move to fit the result. Fourteen tests. Five release gates. One public record.
