Quality Control

Our L-Arginine L-Aspartate is manufactured under strict quality management systems. It is produced to meet exacting standards suitable for pharmaceutical and nutraceutical applications, with typical purity levels exceeding 98.5%. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles. We can supply material compliant with relevant pharmacopeial monographs (such as USP/NF) upon request, ensuring reliable quality and supply chain integrity for your critical formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
