From the other side of the consultation, briefly.

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 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.

Following on from Dr.NateNeph — and this may be the naive question:

What would you measure differently if you were starting again?

Price comparison for compounded supply across sources I've used:

503B Compounding$138cGMP compoundedYes (in-house)
503A Compounding$98Patient-specificVaries

I use the 503B option — best balance of quality, cost, and legality. The brand price is insane but insurance can help if you qualify.

Moderator note: the sourcing question belongs in the vendor section and has been split out. Thread quality here is what the rules are for. Keep it up.
