Every Batch. Third-Party Tested.
Each lot is submitted to an independent laboratory for HPLC purity analysis and mass spectrometry identity confirmation. Results are recorded against the lot number printed on the vial, so material and paperwork never drift apart.
Certificates are published on this site before purchase — not issued on request afterward. Any lot that falls outside specification is rejected.
