Gaithersburg providers order HRT compounds from Promise Pharmacy as a licensed nonresident 503A, not as a local retail counter. Gaithersburg is a mid-size city of about 69,563 residents in Montgomery County (U.S. Census Bureau, Vintage 2023 population estimates). Compounds leave Palm Harbor under 21 U.S.C. § 353a and usually arrive in 2–4 business days.
Service area — shipping, not a storefront
Gaithersburg sits in the Mid-Atlantic region, with about 30,000+ licensed prescribers statewide. This figure is a statewide estimate. We prepare patient-specific prescriptions under 503A and ship them from Florida.
Gaithersburg has about 69,563 residents in Montgomery County (U.S. Census Bureau, Vintage 2023 population estimates). We ship here as its own destination. Typical transit after dispatch is 2–4 business days.
We do not operate a compounding bench in Gaithersburg. Promise Pharmacy is a 503A pharmacy at 31818 US Hwy 19 N, Palm Harbor, FL 34684. Patient-specific compounds for Gaithersburg 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 Gaithersburg.
Every tested batch has a Certificate of Analysis in the provider portal. If a Gaithersburg medical director wants the COA on file before the first patient injection, that is a normal request, not a special favor.
A mid-size market like Gaithersburg needs reliable repeat fills. We support repeat prescriptions for HRT compounds with portal ordering, a named account manager, and five-day compounding.
Standard compounding time is five business days. After that, Gaithersburg 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 Gaithersburg accounts go to our compounding team in Palm Harbor.
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 Maryland Board of Pharmacy can tell you how Maryland expects a nonresident pharmacy to document that.
Federal compounding authority for what we do is 503A of the FD&C Act (21 U.S.C. § 353a): a licensed pharmacy, a patient-specific prescription, USP compounding standards. State permission to land the package in Gaithersburg sits with the Maryland Board of Pharmacy.
Ordering
Active Maryland 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.
How this actually differs
This is a shipping 503A relationship with a Florida pharmacy — not a Gaithersburg storefront comparison.

|---|---|---|
| Gaithersburg transit & packaging | From Palm Harbor; typical 2–4 business days; insulated when the compound needs it | Local pickup or a chain that may not compound this Rx |
| Account model | Credentialed provider account + named manager | Retail profile or PBM network |
| Quality documentation | Third-party testing; COA in the portal | Manufacturer COA |
| Where it is made | Palm Harbor, FL compounding bench | Factory + wholesaler |
| Dosing | Written to the prescription, including custom strengths | Fixed commercial SKUs |
| Ship-to | Clinic or patient in Gaithersburg | Retail counter or mail-order PBM rules |
