Semaglutide and tirzepatide (GLP-1) are prepared under USP <797> sterile-compounding standards against an individual prescription, and shipping reaches all 50 states. Note: 503A pharmacies face restrictions on routinely compounding GLP-1 duplicates of commercially available products now that FDA shortages are over.

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.
Past the state pharmacy license, we could not verify any outside accreditation for this pharmacy.
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].
States Licensed
VialsRx publishes no state-by-state licensure list, so we cannot tell you whether it is licensed where you live. Put that question to your own state board of pharmacy before you fill anything here.
