Independent testing documentation
Batch documentation you can verify. We use TJQXGD Analytical Laboratory for independent chemical analysis, and every report can be checked on the laboratory’s official verification page.
Every report carries a report number issued by the laboratory, so you can confirm it at the source instead of relying on a screenshot.
Approved accounts can request the Certificate of Analysis for any product and lot they are ordering or have received.
We share the laboratory’s PDF report together with its report number.
Enter the report number on the official TJQXGD verification page, or check the PDF itself. The file check runs on your device and compares the report with the laboratory’s official record.
Independent laboratory
