One thing that is still open after Dr.RenalNash’s answer:

What did you change at the same time, and can you separate the two now?

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.

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.

This answered a question I did not know how to ask.

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.
