Missouri has broad telehealth prescribing parity compared with many states, which is why video-first functional, integrative, and longevity clinics in St Charles are a normal account type for us. Controlled substances are still federal: testosterone remains Schedule III, and state telehealth laws do not waive Ryan Haight requirements. For the underlying 503A vs 503B split, we keep a longer explainer on 503A vs 503B compounding.
Federal compounding authority for what we do is 503A of the FD&C Act (21 U.S.C. § 353a): a licensed pharmacy, a patient-specific prescription, USP compounding standards. State permission to land the package in St Charles sits with the Missouri Board of Pharmacy.
