Service area — shipping, not a storefront
We compound tirzepatide in Palm Harbor and ship to licensed providers and their patients in Evanston, Illinois.
Evanston has about 75,070 residents in Cook 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 Evanston sits with the Illinois Department of Financial and Professional Regulation.
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 Illinois Department of Financial and Professional Regulation can tell you how Illinois expects a nonresident pharmacy to document that.
From Palm Harbor, Florida to Evanston, typical ground after dispatch is 2–4 business days. Refrigerated preparations for tirzepatide ship in insulated packaging with season-appropriate cold packs.
Credentialing is not a formality. We check an active Illinois-recognized prescribing license (MD, DO, NP, PA, or equivalent) before the account orders tirzepatide. Testosterone and other controlled substances also need DEA registration.
Independent clinics, multi-site groups, and telehealth programs in Evanston all write tirzepatide differently. The compounding constraint is the same: one patient, one prescription, one labeled package.
We do not operate a compounding bench in Evanston. Promise Pharmacy is a 503A pharmacy at 31818 US Hwy 19 N, Palm Harbor, FL 34684. Patient-specific compounds for Evanston 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 Evanston.
Standard compounding time is five business days. After that, Evanston should plan on 2–4 business days in transit. Discuss any expedited requirements during your onboarding call.
