Quality Control

Our peptide products are manufactured under strict quality management systems. Each batch undergoes comprehensive analytical characterization, including HPLC for purity assessment and mass spectrometry (MS) for identity confirmation. Certificates of Analysis (COA) detailing purity, amino acid analysis, and other relevant specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. This product is hygroscopic (moisture-sensitive). Allow the vial to reach room temperature in a desiccator before opening to minimize moisture uptake. For long-term storage, consider under an inert atmosphere.
