I have been on both brand and compounded, and in the context of compounded supply, my experience has been equivalent with both. The key is finding a reliable 503B pharmacy with independent testing.

That reframing is the part I needed. Printing the relevant bit and taking it with me.

GMP compliance checklist relevant to compounded supply compounding quality:

  • Clean room environment with HEPA filtration
  • Environmental monitoring (viable and non-viable)
  • Personnel training and competency assessment
  • Validated analytical methods for testing
  • Stability testing program
  • Complete batch records and traceability
  • Quality management system with deviation handling

A 503B pharmacy following cGMP should be able to answer questions about ALL of these if you ask. Don't be afraid to ask — it's your health.

Compounding pharmacy licensing verification for compounded supply: before ordering, verify your pharmacy's credentials:

  1. State Board of Pharmacy license — check on your state BOP website
  2. FDA registration (for 503B) — check on fda.gov
  3. DEA registration if handling controlled substances
  4. PCAB accreditation — voluntary but demonstrates commitment to quality
  5. USP <797>/<800> compliance for sterile compounding

This takes 10 minutes of research and could save you from receiving substandard or unsafe medication.
