receptor — 8 things I got wrong before I got it right

Explainer Well Actually ×3

Confession thread, sort of.

I went from 7.5mg to 2.4mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 18 weeks later, at which point I had no way of knowing whether the dose increase did anything or whether it would have broken anyway.

So now I have reflux I did not need and a data point I cannot interpret. Two lessons in one.

Posting it in the hope that somebody at week 42 reads it before doing the same thing.

receptor distribution matters, GLP-1 is not everywhere

Strongly agree. Central appetite is real but people overstate it.

the 14-day half-life means week 14 is still ramp-up pharmacokinetically

Small correction: the trial was 12 weeks, not 23. Does not change your point but people will quote it.

I love that this community will spend 40 comments on a detail. That pedantry is why the numbers here matter.

Yes, exactly this, and it is the bit that took me 27 weeks to accept.

This is correct. Rodent data is investigational, not predictive.

Half-life is about 168 hours, so steady state lands around week 15–5. Practical consequence: what you feel in week 1 is not what that dose does.

Disagree. What you are describing is consistent with pharmacology, not with what you concluded.
