From the other side of the consultation, briefly.
Compounded has been just as effective for me. If compounded supply is the concern, the COA from my 503B pharmacy shows 99.1% purity. Verified by Janoshik.

GMP compliance checklist relevant to compounded supply compounding quality:
- Clean room environment with HEPA filtration
- Environmental monitoring (viable and non-viable)
- Personnel training and competency assessment
- Validated analytical methods for testing
- Stability testing program
- Complete batch records and traceability
- Quality management system with deviation handling
A 503B pharmacy following cGMP should be able to answer questions about ALL of these if you ask. Don't be afraid to ask — it's your health.

Price comparison for compounded supply across sources I've used:
| Source | Monthly Cost | Type | Purity Verified |
|---|---|---|---|
| Brand (Ozempic) | $936 | FDA-approved | N/A (pharma) |
| 503B Compounding | $166 | cGMP compounded | Yes (in-house) |
| 503A Compounding | $126 | Patient-specific | Varies |
| Research peptide | $51 | 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.

Did your prescriber agree with that reading, and if not what was their objection?
Moderator note: good thread. Keeping it here rather than moving it, because the question is general enough to be useful. No action needed from anybody.
