does compounding actually matter or is it forum lore at this point
does compounding actually matter or is it forum lore at this point — that is what I am asking, and I have already read the wiki twice.
Potency and sterility testing on the finished preparation are separate from any certificate covering the starting material. Ask which you are being shown.
Nothing in this thread is medical advice, and the choice between arrangements is one for you and a prescriber who knows your history.
Asked which facility and got a name straight away. Looked it up, found the registration, felt considerably better about the whole thing.
Research-use-only material is not approved for human use and nothing here should be read as a recommendation to use it.
best — the order this archive was captured in
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.
do not assume the concentration matches the branded product

Agreed — and the follow-up question is what the beyond-use date is based on.
Compounded preparations are not approved products and carry no bioequivalence claim. That is a statement about regulatory category, not about quality.
A 503A pharmacy compounds for an identified patient against a prescription. A 503B outsourcing facility registers with the regulator, may produce without patient-specific prescriptions, and is subject to current good manufacturing practice requirements. The two are governed differently and the difference is not cosmetic.
Correction: patient-specific refers to the prescription, not to a bespoke formulation. Common misreading and it changes the argument.
the API source is the question nobody asks and everybody should
Yes. The shortage list is the legal hinge for the whole arrangement and its status is public.
The intake asked me three questions and none of them were about my history. That told me everything I needed to know about the model.
What is the beyond-use date and what is it based on?
What concentration is on the label, and does it match what you were expecting?
Small fix — 503B facilities register with the regulator; 503A pharmacies are licensed by the state board. Different mechanisms.
Not convinced. You are comparing a compounded concentration with a branded one and assuming they match.
Asked for the beyond-use date basis and got a real answer with a stability reference attached. Not universal, apparently.
the label on a compounded vial is a legal document, read 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.
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.
shortage status changes and the whole arrangement changes with it
Asked for potency testing on the finished preparation. They had it. I had assumed they would not.
Switched between two compounded preparations and the concentration on the label was different. Redid the arithmetic on paper before drawing anything.

vikram_mbeki is right about the concentration trap. It breaks arithmetic that has been reliable for months.
