Clinical perspective, offered as context rather than as advice.

I have been on both brand and compounded, and in the context of compounded supply, my experience has been equivalent with both. The key is finding a reliable 503B pharmacy with independent testing.

Compounding pharmacy response time test for compounded supply: I email customer service at odd hours to test responsiveness.

Beyond-use dating (BUD) for compounded supply compounded products:

Lyophilized (unreconstituted): typically 12 months from compounding date
Reconstituted with BAC water: typically 28-30 days refrigerated
Reconstituted with sterile water: typically 48 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.

A narrower follow-up, since the general answer is now clear:

Did your prescriber agree with that reading, and if not what was their objection?

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

SourceMonthly CostTypePurity Verified
Brand (Ozempic)$929FDA-approvedN/A (pharma)
503B Compounding$159cGMP compoundedYes (in-house)
503A Compounding$119Patient-specificVaries
Research peptide$44Not for human useOften 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.
