Quality Control

Our Risperidone is manufactured and tested to meet or exceed current pharmacopeial standards, including USP and EP monographs. Every batch undergoes rigorous analytical testing for identity, assay, related substances, residual solvents, and microbiological quality. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with each shipment to ensure full traceability and regulatory compliance for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to maintain stability and potency.
