503A vs 503B compounding pharmacies for compounded supply — this distinction matters enormously:

I strongly recommend 503B facilities. The FDA oversight and cGMP requirements mean more consistent product quality.

Thank you — that is the clearest version of this I have read, and I have read a lot of them.

For compounded supply users considering compounded for the first time: here's a step-by-step guide:

1. Get a prescription from your doctor (telehealth counts)
2. Research 503B compounding pharmacies with good community reviews
3. Verify their FDA registration and inspection history
4. Request a COA for your specific compound before ordering
5. Start with a 1-month supply to test
6. Consider sending a sample to Janoshik for independent verification
7. Track your response compared to brand (if you were on it previously)

Two pharmacies quoted me last year, one describing itself as 503A and one as 503B, and I assumed 503B just meant bigger until both stopped within…

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.
