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 JenPlateau — and this may be the naive question:
How people are distinguishing a supplier having a bad batch from a supplier on the way out?

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.

Compounding pharmacy licensing verification for compounded supply: before ordering, verify your pharmacy's credentials:
- State Board of Pharmacy license — check on your state BOP website
- FDA registration (for 503B) — check on fda.gov
- DEA registration if handling controlled substances
- PCAB accreditation — voluntary but demonstrates commitment to quality
- USP <797>/<800> compliance for sterile compounding
This takes 10 minutes of research and could save you from receiving substandard or unsafe medication.
Closing the loop on my own question.
Went back through my own correspondence with an earlier supplier and the warning signs were all there in the replies, weeks before the quality changed. I was reading the product and not the behaviour.
