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

SourceMonthly CostTypePurity Verified
Brand (Ozempic)$905FDA-approvedN/A (pharma)
503B Compounding$135cGMP compoundedYes (in-house)
503A Compounding$95Patient-specificVaries
Research peptide$45Not 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 9 months from compounding date
Reconstituted with BAC water: typically 28-30 days refrigerated
Reconstituted with sterile water: typically 7 days (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.

Thank you — that is the clearest version of this I have read, and I have read a lot of them. Adding it to my notes with a link back to this thread.

From the other side of the consultation, briefly.

Regarding compounded supply compounding legality: compounding pharmacies can legally produce semaglutide and tirzepatide while these drugs remain on the FDA shortage list. If/when the shortage resolves, the legal landscape may change.

Stay informed. The FDA shortage list is updated regularly. Current status as of my last check: semaglutide still in shortage, tirzepatide removed from shortage list. This directly impacts compounding availability.

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