Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We provide material manufactured under GMP-like conditions suitable for research and development. Every batch is characterized using advanced analytical techniques including HPLC, MS, and NMR to confirm identity, purity, and peptide content. Certificates of Analysis (COA) with full analytical data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. For long-term storage, lyophilized powder is recommended. The product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and hydrolysis. Store under inert atmosphere if the container is opened frequently.
