This is my experience too, for whatever a second data point is worth. Nothing to add that would improve it.

Adding a me-too, because a thread of one person's experience is not much use. Posting only so the count is not one.

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

SourceMonthly CostTypePurity Verified
Brand (Ozempic)$939FDA-approvedN/A (pharma)
503B Compounding$169cGMP compoundedYes (in-house)
503A Compounding$129Patient-specificVaries
Research peptide$54Not 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.

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.
