Quality Control

This peptide is manufactured under strict cGMP-like conditions to ensure the highest standards of purity and batch-to-batch consistency. Every lot undergoes comprehensive analytical characterization, including reverse-phase HPLC for purity assessment and mass spectrometry (MS) for identity confirmation. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting purity, content, and analytical data. Our quality system is designed to meet the rigorous demands of pharmaceutical R&D and regulatory submissions.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. This product is hygroscopic (moisture-sensitive). For long-term storage, it is recommended to store the lyophilized powder under desiccant. Allow the vial to equilibrate to room temperature before opening to minimize moisture uptake. Solutions should be prepared immediately before use or aliquoted and stored at ≤ -20°C for short periods.
