FDA inspection results for compounding pharmacies selling compounded supply: you can look up any 503B facility's FDA inspection history on the FDA…

For compounded supply users considering compounded for the first time: here's a step-by-step guide:

  1. Get a prescription from your doctor (telehealth counts)
  2. Research 503B compounding pharmacies with good community reviews
  3. Verify their FDA registration and inspection history
  4. Request a COA for your specific compound before ordering
  5. Start with a 1-month supply to test
  6. Consider sending a sample to Janoshik for independent verification
  7. Track your response compared to brand (if you were on it previously)

Compounded has been just as effective for me. If compounded supply is the concern, the COA from my 503B pharmacy shows 99.1% purity. Verified by Janoshik.

Thank you — that is the clearest version of this I have read, and I have read a lot of them. I will report back once I have actually tried it.

From the other side of the consultation, briefly.

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.

Compounding pharmacy response time test for compounded supply: I email customer service at odd hours to test responsiveness. A pharmacy that can't answer questions promptly is a red flag.

My current pharmacy: average response time same day. They answered my questions about sterility testing thoroughly and professionally.

Communication quality is a proxy for operational quality. A pharmacy that communicates well is likely manufacturing well too.
