We do not operate a compounding bench in Naperville. Promise Pharmacy is a 503A pharmacy at 31818 US Hwy 19 N, Palm Harbor, FL 34684. Patient-specific compounds for Naperville 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 Naperville.
Credentialing is not a formality. We check an active Illinois-recognized prescribing license (MD, DO, NP, PA, or equivalent) before the account orders functional medicine compounds. Testosterone and other controlled substances also need DEA registration.

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 Naperville 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.
