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:

Price comparison for compounded supply across sources I've used:
| Source | Monthly Cost | Type | Purity Verified |
|---|---|---|---|
| Brand (Ozempic) | $908 | FDA-approved | N/A (pharma) |
| 503B Compounding | $138 | cGMP compounded | Yes (in-house) |
| 503A Compounding | $98 | Patient-specific | Varies |
| Research peptide | $48 | Not for human use | Often Janoshik |
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.
