Promise Pharmacy is a 503A compounding pharmacy in Palm Harbor, Florida. It prepares patient-specific compounded medications and ships them to licensed providers in Detroit, MI — Detroit is a large city of about 633,218 residents in Wayne County (U.S. Census Bureau, Vintage 2023 population estimates). Typical transit after dispatch is 2–4 business days. There is no Detroit storefront.
Service area — shipping, not a storefront
Detroit sits in the Midwest region, with about 44,000+ licensed prescribers statewide. This figure is a statewide estimate. We prepare patient-specific prescriptions under 503A and ship them from Florida.
Detroit and the Oakland/Macomb/Wayne tri-county area still lose winter days to weather. Refrigerated compounds ship insulated; testosterone and other non-refrigerated 503A preparations use the same tracked ground as the rest of the Midwest.
Michigan has broad telehealth prescribing parity compared with many states, which is why video-first high-volume clinics and groups in Detroit 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.
Michigan permits licensed nonresident pharmacies to ship compounded prescriptions and has a large healthcare provider workforce. Verify a pharmacy license on the Michigan Board of Pharmacy site for current licensure information.
Standard compounding time is five business days. After that, Detroit should plan on 2–4 business days in transit. Discuss any expedited requirements during your onboarding call.

Detroit is in Wayne County. We ship patient-specific compounds to clinics and patients in Detroit.
We do not operate a compounding bench in Detroit. Promise Pharmacy is a 503A pharmacy at 31818 US Hwy 19 N, Palm Harbor, FL 34684. Patient-specific compounds for Detroit are prepared there, then shipped to the clinic or the patient named on the prescription. Local walk-in service and pickup are not available in Detroit.
Winter in Michigan delays trucks and freezes doorsteps. Most preparations for compounded medications in this category do not require frozen packing, but we still choose packaging for the weather the carton will actually sit in. If a Detroit clinic would rather take delivery at the suite than leave a carton on a stoop over a weekend, we ship to the suite. Typical transit after dispatch is 2–4 business days.
