GMP compliance checklist relevant to compounded supply compounding quality:
- Clean room environment with HEPA filtration
- Environmental monitoring (viable and non-viable)
- Personnel training and competency assessment
- Validated analytical methods for testing
- Stability testing program
- Complete batch records and traceability
- Quality management system with deviation handling
A 503B pharmacy following cGMP should be able to answer questions about ALL of these if you ask. Don't be afraid to ask — it's your health.
One thing that is still open after claudia_zurich’s answer:
What actually distinguishes 503A from 503B, in terms of what each may make and from what starting material?

Compounding pharmacy customer here with experience relevant to compounded supply.
I've ordered from 3 different compounding pharmacies over the past year. The quality variation is real — purity ranged from 94% to 101% of label claim based on independent Janoshik testing.
My current compounder (a 503B facility) has been consistently 98-101% purity across 6 orders. I pay $110/month vs $1,320 for brand. The savings are substantial and the product is equivalent in my experience.

Agreed, and the enforcement dates were staggered by category — 503A first, 503B a few weeks later — because outsourcing facilities have manufactured inventory and clinic contracts to unwind while a 503A makes to order.
