Accreditations and Standards

Sterile compounding in this country runs on one rulebook, General Chapter <797> of the United States Pharmacopeia[4]. Depending on what is being made, the finished preparation is then tested for sterility under USP <71>[5] and for bacterial endotoxins under USP <85>[6]. Every pharmacy on this page owes those standards already. What follows is what this one has added on top.

State pharmacy license
The home state board of pharmacy has issued a license. Every pharmacy in the country needs one to open its doors, so treat this as the floor rather than a distinction.
503A
A Section 503A pharmacy. It compounds against a prescription written for one named patient, and its day-to-day regulator is the state board of pharmacy rather than the FDA.
USP 797 sterile compounding
The United States Pharmacopeia chapters that set compounding quality: <795> for non-sterile preparations, <797> for sterile, <800> for hazardous drugs. State boards enforce them at inspection.

What It Compounds

Whether any pharmacy may compound semaglutide or tirzepatide at all turns on where the reference product sits on the FDA Drug Shortage List. When a drug comes off that list the door closes, and it has closed before[7].
