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

Promise Pharmacy is a 503A compounding pharmacy in Palm Harbor, Florida. It prepares patient-specific functional medicine compounds and ships them to licensed providers in Centennial, CO — Centennial is a mid-size city of about 106,883 residents in Arapahoe County (U.S. Census Bureau, Vintage 2023 population estimates). Typical transit after dispatch is 3–5 business days. There is no Centennial storefront.
Service area — shipping, not a storefront
Centennial sits in the Rocky Mountain region, with about 24,000+ licensed prescribers statewide. This figure is a statewide estimate. We prepare patient-specific prescriptions under 503A and ship them from Florida.
Centennial in Arapahoe County (106,883 residents, U.S. Census Bureau, Vintage 2023 population estimates) sits on a mountain-west lane. Winter passes and summer valley heat are why we quote 3–5 business days instead of a single two-day promise.
We do not operate a compounding bench in Centennial. Promise Pharmacy is a 503A pharmacy at 31818 US Hwy 19 N, Palm Harbor, FL 34684. Patient-specific compounds for Centennial 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 Centennial.
Credentialing is not a formality. We check an active Colorado-recognized prescribing license (MD, DO, NP, PA, or equivalent) before the account orders functional medicine compounds. Testosterone and other controlled substances also need DEA registration.
Independent clinics, multi-site groups, and telehealth programs in Centennial all write functional medicine compounds differently. The compounding constraint is the same: one patient, one prescription, one labeled package.
Amy Patel, RPh, our COO, has more than 25 years in sterile compounding. Clinical questions from Centennial accounts go to our compounding team in Palm Harbor.
Every tested batch has a Certificate of Analysis in the provider portal. If a Centennial medical director wants the COA on file before the first patient injection, that is a normal request, not a special favor.
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 Colorado State Board of Pharmacy can tell you how Colorado expects a nonresident pharmacy to document that.
Colorado recognizes compounded medications under its pharmacy practice act and allows direct-to-patient shipping. Verify a pharmacy license on the Colorado State Board of Pharmacy site for current licensure information.
Ordering

These are separate programs on the same 503A account — still shipped from Palm Harbor, still not a Centennial storefront.
