No disagreement with andrew_nyc. One condition attached. Worth adding the genuine exception, because it is real and narrow: a change made for an identified patient where the prescriber determines it produces a significant clinical difference for that patient. A grid of fixed doses offered to everybody is not that, whatever the intake form says.

This is exactly what I could not find anywhere else. Adding it to my notes with a link back to this thread.

Pushing back on andrew_nyc 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.
Worth separating that from compounded supply, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.
