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.

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.

Compounding pharmacy red flag checklist for compounded supply — if ANY of these apply, find a different source:
- No verifiable physical address
- No pharmacist available for consultation
- COA not available or clearly template/fake
- Prices dramatically below market ($30-40/month = suspicious)
- No prescription required
- Ships without cold pack or temperature control
- No batch/lot numbers on product labeling
- Pushes "research use only" products for human injection
Your health depends on product quality. Don't cut corners on source verification.
