Functional Medicine
A retail pharmacy that will not compound the protocol you actually run — that’s why Grand Rapids clinics call. We compound functional medicine compounds patient-by-patient and ship from Florida.

Service area — shipping, not a storefront
Grand Rapids is a mid-size city of about 196,608 residents in Kent County (U.S. Census Bureau, Vintage 2023 population estimates). We support practices in Grand Rapids with clinic delivery and direct-to-patient shipping.
Grand Rapids (196,608 in Kent County, U.S. Census Bureau, Vintage 2023 population estimates) loses winter days to weather. An unattended porch is a worse destination than a staffed suite when the compound is temperature-sensitive. Typical transit is 2–4 business days.
We do not operate a compounding bench in Grand Rapids. Promise Pharmacy is a 503A pharmacy at 31818 US Hwy 19 N, Palm Harbor, FL 34684. Patient-specific compounds for Grand Rapids 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 Grand Rapids.
Every tested batch has a Certificate of Analysis in the provider portal. If a Grand Rapids medical director wants the COA on file before the first patient injection, that is a normal request, not a special favor.
Grand Rapids is in Kent County. We ship patient-specific compounds to clinics and patients in Grand Rapids.
Standard compounding time is five business days. After that, Grand Rapids should plan on 2–4 business days in transit. Discuss any expedited requirements during your onboarding call.
Winter in Michigan delays trucks and freezes doorsteps. Refrigerated preparations for functional medicine compounds ship in insulated packaging with season-appropriate cold packs. If a Grand Rapids 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.
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.
Michigan has broad telehealth prescribing parity compared with many states, which is why video-first functional, integrative, and longevity clinics in Grand Rapids 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.
