[PSA] telehealth is not what most of this community thinks it is
telehealth is not what most of this community thinks it is — with the reasoning, because a rule without a reason gets ignored.
On concentration, which is where I see people actually get hurt.
A compounded vial can be filled at a different concentration from the branded product you were previously using. If you carry over your old arithmetic — same number of units, different mg/mL — you draw a different amount and may not notice for weeks.
Read the label every time you switch. Redo the arithmetic on paper. Write the concentration on the vial. It is the same habit c/reconstitution keeps preaching and this is the case where it actually bites.
Asked for potency testing on the finished preparation. They had it. I had assumed they would not.
The five questions worth asking before you commit to any compounded arrangement.
Which facility, by name. Whether it is a 503A pharmacy or a 503B outsourcing facility. What concentration is on the label. What the beyond-use date is based on. Whether there is potency testing on the finished preparation rather than only on the starting material.
All five are answerable in one email and the pattern of what comes back is more informative than any of the individual answers. An organisation with a quality system finds these questions ordinary.
I will update this if the picture changes rather than quietly leaving it up.
best — the order this archive was captured in
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.

Agreed — and the follow-up question is what the beyond-use date is based on.
the label on a compounded vial is a legal document, read 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.
Cosigning the beyond-use date question. What it is based on tells you whether anybody has done stability work.

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

This is the distinction the whole board runs on. Everything else follows from it.
Paid noticeably more at one clinic than another for what turned out to be the same facility behind both.
do not assume the concentration matches the branded product
Added a jurisdiction tag — the answers to this question are completely different in different countries.
salt forms are the recurring argument and the answer is boring
Agreed. The 503A versus 503B distinction changes who is allowed to make what, and almost every confused thread here starts by ignoring it.

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

ismael_pires is right about the concentration trap. It breaks arithmetic that has been reliable for months.
Right, and the concentration genuinely can differ from the branded product, which breaks people’s arithmetic.
That figure is the starting material purity, not the finished preparation potency. Two different tests.
ask which facility, then ask for their testing
shortage status changes and the whole arrangement changes with it
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.
That is not what patient-specific means. It refers to the prescription, not to a customisation of the formula.
