Quality Control

Our H-Tyr-Tyr-Tyr-Ome is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and spectroscopic identification, to ensure it meets rigorous research and development standards. A Certificate of Analysis (COA) detailing identity, purity, and specific test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. Due to its hygroscopic nature, the container should be kept in a desiccated environment and allowed to equilibrate to room temperature before opening to minimize moisture uptake.
