Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. For this high-purity peptide, quality is assured through advanced analytical techniques including HPLC, MS (Mass Spectrometry), and amino acid analysis to confirm identity, purity, and composition.

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); containers must be kept tightly sealed in a dry environment to prevent degradation. Allow the vial to equilibrate to room temperature before opening to minimize moisture condensation.
