How verification works

A certificate that can't be faked

Each vial's code is tied to a record on our servers. Enter it — or scan the QR — and you see the exact certificate for the vial in your hand.

1

Enter the code or scan

Type the unique code on the label, or scan its QR with any phone camera.

2

We match our record

The code resolves to the certificate stored on our own server — nothing a seller can edit or forge.

3

See the full result

Purity, identity, method and test date — with the certificate PDF to open and download.
