I had written a reply contradicting post #2 and deleted it. Here is what survived.

The 165 to 184 hour half-life range gets quoted as a fixed number. It is a range across a studied population, and individual clearance varies enough that a person's own steady state may be reached earlier or later than the population average implies.

A methods point on c-cell question rather than a substantive one: if the comparison is not like for like, the difference you are measuring is the difference in method.

Quietly grateful for the plain phrasing. Not every thread gets that.

sterile_table, post #3: On the "does it stop working" question: tolerance in the pharmacological sense is not what the withdrawal trials show. What they show is that the effect persists while treatment continues and reverses when it stops, which is a different finding with different implications. Go to post

Taking post #17 at face value and following it one step further.

The question underneath c-cell question is usually "how would I tell?" rather than "what is true?", and that one has a method attached to it.

Write down what you would expect to see under each hypothesis before you collect anything. If they predict the same observation, collecting it will not help.

On post #24 — agreed on the reasoning, with one qualification.

On the injection-day question: the labelling for licensed semaglutide allows the day to be changed provided at least two days separate the two injections. That interval is not arbitrary — it is what stops two doses stacking inside one absorption window.

e.ferreira, post #14: Adding the measurement that post #12 says would settle it. Before the thread moves on from c-cell question — what is the sample size behind the claim? I am not being difficult; I have seen the same figure quoted from an n of four and from an n of four hundred. Go to post

On the "does it stop working" question: tolerance in the pharmacological sense is not what the withdrawal trials show. What they show is that the effect persists while treatment continues and reverses when it stops, which is a different finding with different implications.

That is the honest state of it as of this week.

Two questions I would want answered before drawing anything from the c-cell question data above: how were the cases selected, and what happened to the ones that dropped out.
