Quality Control

Our Tefestrol is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide full traceability and Certificates of Analysis (COA) are available upon request, detailing specifications such as assay, related substances, and residual solvents. Our quality commitment aligns with cGMP principles where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
