Lot numbers and traceability

How one number connects your vial, its certificate and your order.

One lot, one certificate

Every vial carries a lot number. Each lot is tested before release, and its certificate is published under that number in our certificate library.

In your account

When your order ships, the lot number for each item is recorded on the order. Your order history links straight to the certificate for the exact lot you received.

Verification

Each certificate carries a verification key. Enter the certificate number and key on the Verify page to confirm the document is one we issued.
