Quality Control

Our H-Gly-Gly-Trp-Oh is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets high-grade standards suitable for research and development. Certificates of Analysis (COA) with detailed chromatographic data are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed in a desiccated environment away from direct light exposure to maintain stability and purity.
