Hormone Replacement
Fixed commercial HRT doses that do not match the labs sitting on the desk — that’s why Cambridge clinics call. We compound HRT compounds patient-by-patient and ship from Florida.

Promise Pharmacy is a 503A compounding pharmacy in Palm Harbor, Florida. It prepares patient-specific HRT compounds and ships them to licensed providers in Cambridge, MA — Cambridge is a mid-size city of about 118,214 residents in Middlesex County (U.S. Census Bureau, Vintage 2023 population estimates). Typical transit after dispatch is 2–4 business days. There is no Cambridge storefront.
Service area — shipping, not a storefront
We support Cambridge clinics with estradiol, progesterone, DHEA, pregnenolone, BiEst, and TriEst in oral, topical, and sublingual forms, prepared at our 503A pharmacy and shipped to Middlesex County.
Cambridge has about 118,214 residents in Middlesex 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 Cambridge. Promise Pharmacy is a 503A pharmacy at 31818 US Hwy 19 N, Palm Harbor, FL 34684. Patient-specific compounds for Cambridge 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 Cambridge.
Credentialing is not a formality. We check an active Massachusetts-recognized prescribing license (MD, DO, NP, PA, or equivalent) before the account orders HRT compounds. Testosterone and other controlled substances also need DEA registration.
A mid-size market like Cambridge needs reliable repeat fills. We support repeat prescriptions for HRT compounds with portal ordering, a named account manager, and five-day compounding.
Every tested batch has a Certificate of Analysis in the provider portal. If a Cambridge medical director wants the COA on file before the first patient injection, that is a normal request, not a special favor.
From Palm Harbor, Florida to Cambridge, typical ground after dispatch is 2–4 business days. Most preparations for HRT compounds in this category do not require frozen packing, but we still choose packaging for the weather the carton will actually sit in.
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 Cambridge sits with the Massachusetts Board of Registration in Pharmacy.
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 Massachusetts Board of Registration in Pharmacy can tell you how Massachusetts expects a nonresident pharmacy to document that. Massachusetts is also one of the states where nonresident compounding is not a paperwork afterthought — expect extra documentation up front.
Ordering
Active Massachusetts 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.

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