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.

Compounding pharmacy response time test for compounded supply: I email customer service at odd hours to test responsiveness. A pharmacy that can't answer questions promptly is a red flag.

My current pharmacy: average response time 1 hour. They answered my questions about batch-specific COAs thoroughly and professionally.

Communication quality is a proxy for operational quality. A pharmacy that communicates well is likely manufacturing well too.

One thing that is still open after Dr.SportsMedIN’s answer:

Was that from a primary source or from a summary of one?

Vendor communication red flags for compounded supply:

• Won't provide COA before purchase — walk away
• Claims "100% pure" without analytical data — unrealistic
• No physical address or phone number — accountability matters
• Pushes you to buy more than you need — pressure tactics
• Won't answer questions about their compounding process — transparency is key
• Payment only via crypto or wire transfer — legitimate pharmacies accept cards

A legitimate compounding pharmacy operates like a healthcare business, not a gray market dealer.

Compounding pharmacy customer here with experience relevant to compounded supply.

I've ordered from 5 different compounding pharmacies over the past 18 months. 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 5 orders. I pay $120/month vs $1,250 for brand. The savings are substantial and the product is equivalent in my experience.

Re: compounded supply — this applies whether you're using brand or compounded. The clinical principles are the same.
