Quality Control

Our Tetrapeptide-11 is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. All materials undergo rigorous analytical testing, including HPLC for purity and identity confirmation. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory compliance needs.

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 each use to prevent degradation from atmospheric moisture. For long-term storage, consider desiccants or inert atmosphere conditions.
