Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for purity and consistency. Each batch is analyzed to confirm identity, assay, and impurity profiles. Certificates of Analysis (COA) detailing specific test results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
