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].

Frequently Asked Questions

Here is what we can and cannot confirm. Casa Pharma RX operates as a 503A compounding pharmacy out of Stafford, TX. Its authority to operate rests on a state board of pharmacy license and nothing further. No recent public FDA enforcement action has reached our records, and that is not the same as none existing. Enforcement history moves, so put the current standing to your state board of pharmacy before you fill anything.
Casa Pharma RX works out of Stafford, TX. It holds licenses to ship into 1 US state.
Alongside its other compounded preparations, Casa Pharma RX makes compounded semaglutide and compounded tirzepatide. Being a 503A pharmacy, it compounds only against a prescription written for one named patient, with the state board of pharmacy watching.
Two things separate them: who inspects, and how much may be made at once. A 503B outsourcing facility registers with the FDA itself, works to current Good Manufacturing Practices (cGMP), submits to FDA inspection, and may make compounded medication in batches with no named patient attached. A 503A pharmacy cannot do that. It fills a prescription written for one patient, answers mainly to its state board of pharmacy, and works to the USP <797> standard for sterile compounding. Neither route produces an FDA-approved drug.
