Vendor communication red flags for compounded supply:
- Won't provide COA before purchase — walk away
- Claims "100% pure" without analytical data — unrealistic
- No physical address or phone number — accountability matters
- Pushes you to buy more than you need — pressure tactics
- Won't answer questions about their compounding process — transparency is key
- Payment only via crypto or wire transfer — legitimate pharmacies accept cards
A legitimate compounding pharmacy operates like a healthcare business, not a gray market dealer.

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 2 hours. They answered my questions about storage conditions thoroughly and professionally.
Communication quality is a proxy for operational quality. A pharmacy that communicates well is likely manufacturing well too.
One thing that is still open after PedsEndoPhilly’s answer:
What actually works on a prior-authorisation denial, as opposed to the list of things that sound like they should work?

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.

Price comparison for compounded supply across sources I've used:
| Source | Monthly Cost | Type | Purity Verified |
|---|---|---|---|
| Brand (Ozempic) | $1059 | FDA-approved | N/A (pharma) |
| 503B Compounding | $139 | cGMP compounded | Yes (in-house) |
| 503A Compounding | $129 | Patient-specific | Varies |
| Research peptide | $49 | 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.
