What the certificate tells you

01

Task number and batch

The lab's task number is on every report. The batch must match the label on your vial or bottle.

02

Test requested and result

What the lab was asked to measure and what it found, exactly as printed. We transcribe it, we never restate it. Not every report carries a purity line: blends and some compounds are reported by content only.

03

Verify key

Each report ends with a unique key. Enter it at janoshik.com/verify to confirm the report is genuine.
