[Question] does anyone get a COA from their compounding pharmacy
Question in the title, detail here: does anyone get a COA from their compounding pharmacy.
Paid noticeably more at one clinic than another for what turned out to be the same facility behind both.
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.
Asked for potency testing on the finished preparation. They had it. I had assumed they would not.
Happy to answer the boring questions. Those are usually the ones worth asking.

Reminder that nothing here is medical advice and this board cannot tell you which arrangement to choose.
Agreed on potency testing of the finished preparation. That is a different question from the purity of the starting material.
Careful. Naming a clinic without describing what actually happened turns this into a different kind of thread.
compounded is not generic, there is no equivalence claim

Agreed — and the follow-up question is what the beyond-use date is based on.
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.
Push back: "compounded is fine because a pharmacy made it" skips every question this board exists to ask.
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.
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.
Concentration on the compounded vial was different from what I had been using and I nearly did the arithmetic on autopilot.
Correction: patient-specific refers to the prescription, not to a bespoke formulation. Common misreading and it changes the argument.
