For weight-loss clinics and obesity-medicine practices in Cambridge, Promise Pharmacy compounds semaglutide and tirzepatide on a patient-specific prescription, then ships from Palm Harbor, Florida. Cambridge is a mid-size city of about 118,214 residents in Middlesex County (U.S. Census Bureau, Vintage 2023 population estimates). Fulfillment target is five business days in the pharmacy, plus 2–4 business days in transit.
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 semaglutide and tirzepatide 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.
Independent clinics, multi-site groups, and telehealth programs in Cambridge all write GLP-1 compounds differently. The compounding constraint is the same: one patient, one prescription, one labeled package — not a crate of stock bottles for the fridge.
Amy Patel, RPh, our COO, has more than 25 years in sterile compounding. Clinical questions from Cambridge accounts go to the same compounding team — not a city-specific pharmacist we invented for this URL.
From Palm Harbor, Florida to Cambridge, typical ground after dispatch is 2–4 business days. Refrigerated GLP-1 compounds ship in insulated packaging with season-appropriate cold packs — a cardboard mailer is not a plan.
Massachusetts has broad telehealth prescribing parity compared with many states, which is why video-first weight-loss clinics and obesity-medicine practices in Cambridge are a normal account type for us. Controlled substances are still federal: testosterone remains Schedule III, and Ryan Haight is not waived by a friendly state telehealth statute. For the underlying 503A vs 503B split, we keep a longer explainer on 503A vs 503B compounding rather than restating it on every city URL.
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.
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 GLP-1 compounds for Cambridge are prepared there, then shipped to the clinic or the patient named on the prescription. If you need a walk-in window on Middlesex County streets, we are the wrong vendor — and we would rather say that than pretend otherwise.
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.
