Promise Pharmacy is a 503A compounding pharmacy in Palm Harbor, Florida. It prepares patient-specific tirzepatide 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
We compound tirzepatide in Palm Harbor and ship to licensed providers and their patients in Detroit, Michigan.
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 weight-loss clinics and telehealth programs 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.
USP chapters 795, 797, and 800 are the compounding standards we work to. Chapter 797 addresses sterile compounding, and Chapter 800 addresses hazardous drug handling. The Michigan Board of Pharmacy can tell you how Michigan expects a nonresident pharmacy to document that.
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.
Amy Patel, RPh, our COO, has more than 25 years in sterile compounding. Clinical questions from Detroit accounts go to our compounding team in Palm Harbor.
A large market like Detroit needs reliable repeat fills. We support repeat prescriptions for tirzepatide with portal ordering, a named account manager, and five-day compounding.
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. Refrigerated preparations for tirzepatide ship in insulated packaging with season-appropriate cold packs. 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.
Ordering
Active Michigan prescribing license (and DEA if you will order controlled substances). Approval is typically within 48 hours — not instant.
Every 503A compound requires a patient-specific prescription in the portal.
Five business days on the Palm Harbor bench, with third-party testing on lots that require it.
Clinic or patient address. Typical transit 2–4 business days. Refrigerated compounds go insulated.
