Clinical perspective, offered as context rather than as advice.

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.

503A vs 503B compounding pharmacies for compounded supply — this distinction matters enormously:

I strongly recommend 503B facilities. The FDA oversight and cGMP requirements mean more consistent product quality.

Same pattern here, and in the same order. The detail I would add is minor and it is already implied above.

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 3 inspections.
