503A vs 503B compounding pharmacies for compounded supply — this distinction matters enormously:
| Feature | 503A | 503B |
|---|---|---|
| Regulation | State Board of Pharmacy | FDA-registered |
| Prescription | Required (patient-specific) | Can compound without patient Rx |
| Testing | Varies by state | cGMP required |
| Scale | Small batches | Larger production |
| Quality consistency | Variable | Generally higher |
I strongly recommend 503B facilities. The FDA oversight and cGMP requirements mean more consistent product quality.
A narrower follow-up, since the general answer is now clear:
How would you tell the difference between that and the alternative explanation?

Price comparison for compounded supply across sources I've used:
| Source | Monthly Cost | Type | Purity Verified |
|---|---|---|---|
| Brand (Ozempic) | $990 | FDA-approved | N/A (pharma) |
| 503B Compounding | $170 | cGMP compounded | Yes (in-house) |
| 503A Compounding | $100 | Patient-specific | Varies |
| Research peptide | $55 | 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.

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.
Closing the loop on my own question.
Follow-up — getting the denial reason in writing was the step that mattered. It named the criterion, and the criterion was a document I already had.
