Quality Control

Our 5-Hydroxy L-Tryptophan is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for assay and purity, to ensure it meets stringent specifications for pharmaceutical and nutraceutical use. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption.
