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

Agreed, and the enforcement dates were staggered by category — 503A first, 503B a few weeks later — because outsourcing facilities have manufactured inventory and clinic contracts to unwind while a 503A makes to order.

Agreed on the mechanism, with the caveat that the head-to-head used semaglutide 1mg, not 2.4mg.

Genuinely useful, thank you. I had the facts and not the framework. Adding it to my notes with a link back to this thread.

Pushing back on Dr.NateNeph here. 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.

One concrete data point for the thread. Worth stating the units and the reference range whenever you post a number here. A large fraction of the apparent disagreement in these threads is two people using different units and both being right.

Moderator note: two posts asking for a source have been merged into one. Please search the thread before asking again. Report rather than reply if it drifts again.
