Quality Control

Our Cys-Gly is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC for purity, chiral analysis, and residual solvent screening to ensure it meets high-grade standards for research and development. A detailed Certificate of Analysis (COA) providing lot-specific data is available for every shipment to guarantee traceability and consistency.

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 tightly sealed after opening to prevent absorption of atmospheric moisture. For long-term storage, consider desiccants or inert atmosphere.
