Quality Control

Our Cyclo(Glycyl-Prolyl-Phenylalanyl-Valyl-Phenylalanyl-Phenylalanyl) is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, MS for identity confirmation, and chiral analysis to ensure sequence integrity. Certificates of Analysis (COA) detailing all specifications are provided and available upon request to support your quality assurance protocols.

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 in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
