Adding the clinical framing, because it changes how the question reads.
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.
