TB-500 5mg

A certificate of analysis (COA) is the third-party report for a specific lot: what the material was tested for, which methods were used, and what the results were. Each lot number receives its own COA.

When a product shows "COA pending," the batch is in testing or the certificate is still being filed. We do not publish a figure without the test report to back it up. Once the lot clears testing, the certificate is published and filed by batch number.
