From the other side of the consultation, briefly. It helps to say which part of this you are uncertain about. A precise question gets a precise answer; a general one gets everybody’s favourite anecdote.
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?

I read this differently. The confidence in this thread is running ahead of the evidence, and I would rather the uncertainty were stated than smoothed over because it is unsatisfying.

No disagreement with hyun_seoul. 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.
Moderator note: the sourcing question belongs in the vendor section and has been split out. Report rather than reply if it drifts again.
