The primary certificates name Bioviridian Inc. as the laboratory that tested the submitted sample for identity, purity and content. Additional results are attributed to their issuing laboratory alongside the primary measurements. Every certificate we hold is published in full: the original PDF and its certificate ID, which you can take to the laboratory to check the report yourself.

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.

They are listed under SEM-20260828-01, the 30 mg semaglutide lot from that fill, as our best attribution; the laboratory did not confirm the lot.
