Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is characterized using advanced analytical techniques including HPLC and mass spectrometry to confirm identity, purity, and peptide content. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request. We adhere to GMP principles for manufacturing control where applicable to support research and development needs.

Storage

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