Mounjaro pen vs compounded vial - pros and cons? — July 2024

Dr.RaviCardio said:

The shortage clause is the answer to the second question and it is a subtraction rather than an addition.

Pushing back on Dr.RaviCardio here. A research-chemical supplier selling lyophilised powder labelled research use only is not compounding and is not claiming to. It is a different legal universe with no pharmacy oversight, no patient relationship and no content guarantee, and conflating the two in these threads helps nobody.

Worth separating that from tirzepatide, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.

Correct me if the detail matters more than I have assumed.

One concrete data point for the thread. Practical numbers: half-life about 5 days, steady state 3 to 4 weeks, ladder 2.5 / 5 / 7.5 / 10 / 12.5 / 15mg, and the maintenance doses with published data behind them are 5, 10 and 15mg.

Adding the part of the answer the thread has not reached. Steady state is faster than people expect: half-life about five days, so you are at plateau in roughly three to four weeks rather than five. That matters when you are deciding whether a dose step has finished expressing itself.

Following on from rick_sfbay — and this may be the naive question:

Why a shortage listing created a legal pathway at all, since a shortage is a supply fact rather than a permission?

Reporting back.

The bulks-list asymmetry was the piece I had missed entirely. It explains why one of my two pharmacies is still arguing it can supply and the other simply stopped.
