Quality Control

Our Zosterin is produced under strict quality management systems to ensure batch-to-batch consistency and purity. The product undergoes comprehensive testing, including assays for key bioactive markers, heavy metals, microbial limits, and residual solvents, aligning with industry standards for botanical extracts. A Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a low-humidity environment to prevent moisture absorption and maintain stability.
