503A & 503B Sourcing & Distribution
ExaVeyra Sciences partners with FDA-registered 503A and 503B facilities for compounding sourcing and distribution. Headquartered in Miami, FL, with operations across the United States.
Understanding 503A vs 503B
503A pharmacies prepare compounded medications for individual patients based on prescriptions. They follow state pharmacy board oversight and use FDA-approved ingredients. 503A compounding is ideal for patient-specific formulations and tailored protocols.
503B outsourcing facilities manufacture medications in bulk under FDA Current Good Manufacturing Practices (CGMP). They register with the FDA, can ship interstate, and supply office-use products for clinics—such as injectable nutrients, biologics, and compounded preparations for in-office use without individual prescriptions.
