[REVIEW] Tailor Made Compounding — my results so far

Dr.CardioMD said:

Resolution therefore closed the doors unevenly, and the asymmetry follows from the bulks lists.

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. 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.

That is the short version; the long version is somebody else's post.

My pharmacy stopped supplying with three weeks notice and a letter that explained nothing, so I went and read the statute.

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 1 Form 483 observations in their last 2 inspections.

This is public information. Use it. Link: fda.gov/inspections-compliance-enforcement-and-criminal-investigations

Price comparison for compounded supply across sources I've used:

I use the 503B option — best balance of quality, cost, and legality. The brand price is insane but insurance can help if you qualify.

A narrower follow-up, since the general answer is now clear:

What actually distinguishes 503A from 503B, in terms of what each may make and from what starting material?

Closing the loop on my own question.

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.
