Quality Control

Our L-Citrulline Dl-Malate 2:1 is manufactured under strict quality management systems. Each batch is tested to ensure it meets high-purity standards suitable for nutraceutical and pharmaceutical applications. Certificates of Analysis (COA) documenting identity, purity, and safety parameters are provided with every shipment. We can supply grades compliant with relevant specifications, including FCC and USP, upon request.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
