Quality Control

Our peptide products undergo rigorous quality testing to ensure compliance with industry standards for research and pharmaceutical applications. Each batch is characterized using advanced analytical techniques including HPLC for purity and MS for identity confirmation. Certificates of Analysis (COA) detailing purity, content, and analytical data 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) and should be handled under anhydrous conditions to maintain stability. Allow the vial to equilibrate to room temperature before opening to minimize moisture condensation.
