Promise Pharmacy is a 503A compounding pharmacy in Palm Harbor, Florida. It prepares patient-specific tirzepatide 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
Most Cambridge clinics that call us are not shopping for a second storefront. They already have a protocol. What they do not have is a 503A bench that will compound tirzepatide for subcutaneous injection, plus troches and sublingual drops when the protocol calls for them for the patient on the Rx and get it to Middlesex County without turning into a shortage story.
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.
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 — not a slogan. Sterile work is a 797 problem; hazardous handling is an 800 problem. 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.
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.
Standard compounding time is five business days. After that, Cambridge should plan on 2–4 business days in transit. If your protocol cannot survive that clock, say so on the onboarding call — expedite exists, magic does not.
Independent clinics, multi-site groups, and telehealth programs in Cambridge all write tirzepatide differently. The compounding constraint is the same: one patient, one prescription, one labeled package — not a crate of stock bottles for the fridge.
