How to Verify Your Compounding Pharmacy Is Legitimate
A practical, step-by-step guide to confirming your compounding pharmacy is properly licensed, registered, and safe.
Before trusting any compounding pharmacy with your GLP-1 medication, take a few minutes to verify their credentials. This guide walks you through exactly how to do it using free, publicly available databases.
Step 1: Check FDA Registration (503B Facilities)
FDA Outsourcing Facility Database
- 1. Visit FDA.gov and navigate to the Registered Outsourcing Facilities page
- 2. Search by pharmacy name, city, or state
- 3. Confirm the facility appears on the list with active registration
- 4. Note any FDA warning letters or enforcement actions linked to the facility
If a pharmacy claims to be a 503B outsourcing facility but does not appear in the FDA database, do not use them.
Important: 503A pharmacies (traditional compounding pharmacies) are not required to register with the FDA. They are regulated by state pharmacy boards instead. If a pharmacy is a 503A, skip to Step 2.
Step 2: Verify State Pharmacy Board License
State License Verification
- 1. Identify the state where the pharmacy is physically located
- 2. Visit that state's Board of Pharmacy website
- 3. Use the license lookup or verification tool
- 4. Search by pharmacy name or license number
- 5. Confirm the license is active and in good standing
- 6. Check for any disciplinary actions, fines, or restrictions
Every compounding pharmacy -- both 503A and 503B -- must hold an active state pharmacy license. If they compound and ship to patients in other states, they typically need non-resident pharmacy licenses in those states as well.
Step 3: Check for PCAB or Other Accreditations
The Pharmacy Compounding Accreditation Board (PCAB), administered by the Accreditation Commission for Health Care (ACHC), offers a voluntary accreditation program for compounding pharmacies. While not required, PCAB accreditation demonstrates a pharmacy's commitment to quality:
- Comprehensive on-site inspection of facilities and processes
- Review of quality assurance protocols
- Staff competency evaluation
- Ongoing compliance monitoring
You can verify PCAB accreditation at the ACHC website by searching for the pharmacy name.
Step 4: Request Documentation
A legitimate compounding pharmacy should be willing and able to provide the following documentation upon request:
Documentation Checklist
- Certificate of Analysis (COA) for API: From their semaglutide/tirzepatide supplier showing purity, identity, and quality
- Finished product potency testing: Third-party lab results confirming the labeled concentration is accurate
- Sterility testing results: Confirming the injectable product is free of microbial contamination
- Endotoxin testing results: Confirming acceptable endotoxin levels for injectable use
- State pharmacy license number: Verifiable through the state board
- FDA registration number (503B): If they claim 503B status
Step 5: Contact the Pharmacy Directly
Questions to Ask
- • Are you a 503A or 503B compounding pharmacy?
- • Can I speak with the pharmacist-in-charge?
- • Where do you source your semaglutide/tirzepatide API?
- • Do you use semaglutide base or semaglutide sodium?
- • What third-party testing do you perform on finished products?
- • Can you provide your most recent potency and sterility test results?
- • What is the beyond-use dating on your compounded semaglutide?
- • How do you ship medications to maintain cold chain?
A reputable pharmacy will welcome these questions. Evasiveness or refusal to answer should be treated as a red flag.
