[PSA] compounding is not what most of this community thinks it is
compounding is not what most of this community thinks it is, written plainly and without the jargon that usually swallows this topic.
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.
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.
Compounded preparations are not approved products and carry no bioequivalence claim. That is a statement about regulatory category, not about quality.
Tell me where this is wrong. That is the useful part of posting it.

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.
ask which facility, then ask for their testing

Careful. Naming a clinic without describing what actually happened turns this into a different kind of thread.
What is the beyond-use date and what is it based on?
Careful.
jonas_eriksen is right about the concentration trap. It breaks arithmetic that has been reliable for months.
the shortage list is the whole legal hinge and people skip it
ask what the beyond-use date is based on
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.
do not assume the concentration matches the branded product
a 503B has to register and report, so there is a paper trail to ask for
the pharmacy and the prescriber are two separate questions
What concentration is on the label, and does it match what you were expecting?
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.
Not convinced. You are comparing a compounded concentration with a branded one and assuming they match.
shortage status changes and the whole arrangement changes with it
Right, and the concentration genuinely can differ from the branded product, which breaks people’s arithmetic.
Asked for the beyond-use date basis and got a real answer with a stability reference attached. Not universal, apparently.
Paid noticeably more at one clinic than another for what turned out to be the same facility behind both.
the API source is the question nobody asks and everybody should

This is the distinction the whole board runs on. Everything else follows from it.
a telehealth intake that asks nothing has told you what it is

Disagreeing with this bit: registration is not equivalence, and the two get run together constantly.

Adding one thing — ask for the facility name. Most will give it, and the ones that will not have answered you.
