Quality Control

Our peptide products are manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity and MS for identity confirmation. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting the specifications and test results. We support research requiring compliance with cGMP guidelines for non-clinical use.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. This product is hygroscopic (moisture-sensitive). For long-term storage, it is recommended to store the peptide desiccated. Allow the vial to warm to room temperature before opening to minimize moisture absorption.
