Quality Control

Our Phenylalanyl-Leucyl-Glutamyl-Glutamyl-Valine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and development applications. A Certificate of Analysis (COA) detailing specific batch results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
