Third-Party Testing
To eliminate manufacturer bias, every batch is tested by an independent third-party laboratory. We do not self-report purity; results come from external analytical labs using validated methods.
Independent Verification
Samples from each production batch are sent to an independent laboratory for analysis. The lab issues a Certificate of Analysis reporting identity and purity results obtained through validated analytical methods.
Methods Used
Identity is confirmed by mass spectrometry (LC-MS), which verifies the molecular weight of the target compound. Purity is quantified by reverse-phase HPLC, which separates the target from impurities and reports the main-peak area percent.
Why Independence Matters
Independent testing removes the conflict of interest that exists when a manufacturer reports its own results. Third-party data gives researchers confidence that reported purity reflects an unbiased measurement.
