Quality Control

Our peptide is manufactured under strict cGMP-like conditions to ensure batch-to-batch consistency and traceability. Every lot undergoes comprehensive analytical characterization, including HPLC for purity and MS for identity confirmation. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting purity, peptide content, and residual solvent levels. We support compliance with ISO 9001 quality management standards.

Storage

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