Has anyone dealt with fda warning letters to compounding pharmacies?

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.

Worth adding the genuine exception, because it is real and narrow: a change made for an identified patient where the prescriber determines it produces…

Genuinely useful, thank you. I had the facts and not the framework. I will report back once I have actually tried it.

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.

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…

Beyond-use dating (BUD) for compounded supply compounded products:

Lyophilized (unreconstituted): typically 9 months from compounding date
Reconstituted with BAC water: typically 28-30 days refrigerated
Reconstituted with sterile water: typically 7 days (no preservative!)

Always use BAC water for multi-dose vials. Sterile water has no preservative and supports bacterial growth after first puncture. This is a common and potentially dangerous mistake.
