Compounding pharmacy red flag checklist for compounded supply — if ANY of these apply, find a different source: No verifiable physical address No…

Can confirm the pattern TrialNerd_Beth describes. One addition: an unstated method makes a report close to uninterpretable. "99% pure" without the technique, the standard and the conditions is a claim, not a measurement.

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.

Clinical perspective, offered as context rather than as advice.

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.
