Quality Control

Our L-α-Glutamyl-L-Cysteinylglycine Glutathione is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets high-grade specifications suitable for pharmaceutical and nutraceutical applications. Certificates of Analysis (COA) are available upon request, detailing compliance with relevant standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. This product is hygroscopic (moisture-sensitive) and easily oxidized; therefore, it is recommended to store under an inert atmosphere such as nitrogen or argon after opening to maintain potency and prevent degradation.
