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.

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.

This is exactly what I could not find anywhere else. Printing the relevant bit and taking it with me.

Mine went the same way, slower.
