BethLabQueen said:Resolution therefore closed the doors unevenly, and the asymmetry follows from the bulks lists.
I read this differently from BethLabQueen, on substance rather than tone. A research-chemical supplier selling lyophilised powder labelled research use only is not compounding and is not claiming to. It is a different legal universe with no pharmacy oversight, no patient relationship and no content guarantee, and conflating the two in these threads helps nobody.
PharmD_Rodriguez said: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…
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.

FDA inspection results for compounding pharmacies selling compounded supply: you can look up any 503B facility's FDA inspection history on the FDA website.
Check for: Form 483 observations (violations), warning letters, and recall history. A clean inspection record is a strong indicator of quality. My pharmacy has had 0 Form 483 observations in their last 4 inspections.

What actually distinguishes 503A from 503B, in terms of what each may make and from what starting material?
OP back with an update, since a thread like this is useless without one.
The bulks-list asymmetry was the piece I had missed entirely. It explains why one of my two pharmacies is still arguing it can supply and the other simply stopped.
