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.
Following on from ingrid_STO — and this may be the naive question:
Why a shortage listing created a legal pathway at all, since a shortage is a supply fact rather than a permission?

For compounded supply users considering compounded for the first time: here's a step-by-step guide:
- Get a prescription from your doctor (telehealth counts)
- Research 503B compounding pharmacies with good community reviews
- Verify their FDA registration and inspection history
- Request a COA for your specific compound before ordering
- Start with a 1-month supply to test
- Consider sending a sample to Janoshik for independent verification
- Track your response compared to brand (if you were on it previously)

The bulks-list asymmetry was the piece I had missed entirely. It explains why one of my two pharmacies is still arguing it can supply and the other simply stopped.

No disagreement with Dr.ReproEndo. One condition attached. Worth adding the genuine exception, because it is real and narrow: a change made for an identified patient where the prescriber determines it produces a significant clinical difference for that patient. A grid of fixed doses offered to everybody is not that, whatever the intake form says.
If somebody has the primary source to hand I would rather cite it than paraphrase it.
