Scan the vial.
Read the lab report.

Identity, purity and content are measured by Bioviridian Inc., an independent analytical laboratory. Every certificate we hold is published in full — the raw PDF, and the code that lets you verify it at the lab directly rather than taking our word for it.

Data Matrix code for lot SEM-20260811-01

How it works

The Data Matrix printed on each vial encodes that vial’s production lot. Point a phone camera at it and it opens the certificate for the material in your hand — not a generic page, not a batch average. This one is real: it opens lot SEM-20260811-01.
