O'Fallon is in St. Charles County. We ship patient-specific compounds to clinics and patients in O'Fallon.
Credentialing is not a formality. We check an active Missouri-recognized prescribing license (MD, DO, NP, PA, or equivalent) before the account orders BHRT compounds. Testosterone and other controlled substances also need DEA registration.
Standard compounding time is five business days. After that, O'Fallon should plan on 2–4 business days in transit. Discuss any expedited requirements during your onboarding call.
Missouri accepts nonresident pharmacy licenses and supports telehealth prescribing for most medication categories. Verify a pharmacy license on the Missouri Board of Pharmacy site for current licensure information.
Missouri has broad telehealth prescribing parity compared with many states, which is why video-first BHRT and integrative practices in O'Fallon 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.
