Every batch goes through a comprehensive testing process, and we provide complete Certificate of Analysis (COA) documentation.

  • Purity verification: Minimum 99.8% confirmed purity via HPLC
  • LCMS screening: Molecular identity and structure verification
  • Heavy metals analysis: Screening for contaminants such as lead, mercury, cadmium, and arsenic
  • Endotoxin analysis: Bacterial contamination safety screening
  • Sterility testing: Microbiological safety confirmation

If any batch does not meet our purity standards, we replace it free or provide a full refund.
