Quality Control

Our L-Ornithine (3-Methyl-2-Oxopentanoate) is manufactured under strict quality management systems. Each batch undergoes rigorous 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 provided with every shipment to guarantee supply chain transparency and product consistency.

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 in a low-humidity environment to prevent degradation and clumping.
