how much of what we believe about API source actually comes from telehealth threads
how much of what we believe about API source actually comes from telehealth threads. I am not trying to be the "source?" guy. I would just like a source.
Concentration on the compounded vial was different from what I had been using and I nearly did the arithmetic on autopilot.
Asked for the beyond-use date basis and got a real answer with a stability reference attached. Not universal, apparently.
Switched between two compounded preparations and the concentration on the label was different. Redid the arithmetic on paper before drawing anything.
If two or three other people have done the same thing we might actually learn something. Alone it is an anecdote.

Compounded preparations are not approved products and carry no bioequivalence claim. That is a statement about regulatory category, not about quality.
This. Compounded preparations carry no equivalence claim, and treating them as generics is a category error people make constantly.
Asked for potency testing on the finished preparation. They had it. I had assumed they would not.
Why "compounded" is not "generic", written out because the confusion is constant.
A generic is an approved product demonstrated to be bioequivalent to a reference. A compounded preparation is made for a patient or, in the case of an outsourcing facility, under a different regulatory route entirely. It carries no equivalence claim and it is not required to demonstrate one.
That is not a quality judgement. Plenty of compounded preparations are made carefully in facilities with real testing programmes. It is a statement about what has and has not been established, and the difference matters when people assume the two are interchangeable.
Reminder that nothing here is medical advice and this board cannot tell you which arrangement to choose.
the shortage list is the whole legal hinge and people skip it
A beyond-use date derived from published stability data means something different from one assigned by default rule. Asking which is a fair question and the answer is usually available.
503A or 503B — do you know which?
Yes. The shortage list is the legal hinge for the whole arrangement and its status is public.
What concentration is on the label, and does it match what you were expecting?
[deleted]
Agreed on potency testing of the finished preparation. That is a different question from the purity of the starting material.
Was there potency testing on the finished preparation, or only on the starting material?
Correction: patient-specific refers to the prescription, not to a bespoke formulation. Common misreading and it changes the argument.
a telehealth intake that asks nothing has told you what it is
What is the beyond-use date and what is it based on?
