FDA inspection results for compounding pharmacies selling compounded supply: you can look up any 503B facility's FDA inspection history on the FDA website.
Check for: Form 483 observations (violations), warning letters, and recall history. A clean inspection record is a strong indicator of quality. My pharmacy has had 0 Form 483 observations in their last 4 inspections.

Dr.RenalNash said:Agreed, and the enforcement dates were staggered by category — 503A first, 503B a few weeks later — because outsourcing facilities have manufactured…
Saving this. It is the first explanation that did not require me to already understand it.

Beyond-use dating (BUD) for compounded supply compounded products:
Lyophilized (unreconstituted): typically 6 months from compounding date
Reconstituted with BAC water: typically 28-30 days refrigerated
Reconstituted with sterile water: typically 24 hours (no preservative!)
Always use BAC water for multi-dose vials. Sterile water has no preservative and supports bacterial growth after first puncture. This is a common and potentially dangerous mistake.

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 1 hour. They answered my questions about batch-specific COAs thoroughly and professionally.
Communication quality is a proxy for operational quality. A pharmacy that communicates well is likely manufacturing well too.
