Each certificate of analysis on this page is issued by an independent, third-party laboratory for a specific production batch. Reading one takes only a minute, and it tells you exactly what was tested and what the results were. However, a report is only useful if you know what to look for, so here is a quick guide to the main sections.

Batch or lot number – identifies the production batch the report applies to.
Identity – confirms the sample is the compound named on the report.
Purity – reported as a percentage measured by high-performance liquid chromatography (HPLC). FitFox Labs only lists batches that test at ≥99%.
Test date and laboratory – most certificates also show when the analysis was carried out and which laboratory performed it.

In addition, independent testing matters because it gives an objective check on every batch. The results come from a laboratory that has no stake in the sale, so the identity and purity data on each report give you a clear basis for planning your research and comparing suppliers.

We add new certificates of analysis as new batches are tested. If you need the report for a batch that is not listed here, please contact our team, or browse the full range of COA-verified products in our store.
