someone explain compounding to me like I have not read a paper in years. If this has been answered properly somewhere, link me and I will delete.
Potency and sterility testing on the finished preparation are separate from any certificate covering the starting material. Ask which you are being shown.
The shortage list is the legal hinge: the permissions that allow certain compounding to happen at scale are tied to a drug’s shortage status, which changes.
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.
Tell me where this is wrong. That is the useful part of posting it.

Salt form matters for mass: a preparation specified as one salt and dosed as the free base gives you a different amount of peptide for the same number on the label.
Correction: patient-specific refers to the prescription, not to a bespoke formulation. Common misreading and it changes the argument.
Asked for potency testing on the finished preparation. They had it. I had assumed they would not.
compounded is not generic, there is no equivalence claim
Careful. Naming a clinic without describing what actually happened turns this into a different kind of thread.
ask which facility, then ask for their testing
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.
ask what the beyond-use date is based on
Right, and the concentration genuinely can differ from the branded product, which breaks people’s arithmetic.
Switched between two compounded preparations and the concentration on the label was different. Redid the arithmetic on paper before drawing anything.
Cosigning the beyond-use date question. What it is based on tells you whether anybody has done stability work.
I would not read the price difference as a quality signal. Most of it is the consultation model, not the vial.
