Quality Control

Our L-α-Phosphatidylserines, Brain, Porcine is produced and tested under strict quality systems. Each batch is analyzed to ensure high purity and consistency, with specifications tailored to meet the demands of pharmaceutical and nutraceutical applications. Certificates of Analysis (COA) documenting identity, purity, and related substances are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Under these conditions, the product is typically stable for at least two years. Allow the sealed container to reach room temperature before opening to minimize moisture condensation.
