Quality Control

Every batch of our peptide is synthesized and purified under strict cGMP-like conditions to ensure the highest standards of identity, purity, and potency. Quality is verified through a comprehensive battery of analytical tests including HPLC for purity, MS for identity confirmation, and amino acid analysis. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality attributes. We support compliance with global regulatory frameworks for research materials.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. This product is hygroscopic (moisture-sensitive). For long-term storage, it is recommended to store the lyophilized powder under an inert atmosphere or in a desiccated environment. Allow the vial to equilibrate to room temperature before opening to minimize moisture uptake.
