[Discussion] half-life is doing more work than we give it credit for

Discussion Receipts ×2 Sourced ×3 Long Haul ×3

Confession thread, sort of.

I went from 0.25mg to 10mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 13 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 60 reads it before doing the same thing.

Stomach physiology changed when I moved up to 7.5mg. Gastric emptying lag is the whole story.

Rodent, human, or in vitro?

receptor distribution matters, GLP-1 is not everywhere

central appetite signalling is real but people overweight it

Yes, exactly this, and it is the bit that took me 43 weeks to accept.

Stomach physiology changed when I moved up to 1.7mg. Gastric emptying lag is the whole story.

do not extrapolate rodent data to human dosing without saying so

Crossposting this to c/meta because the people who need it are not reading this community.

Not convinced. The evidence does not support that reading.

the half-life is half-life, affects steady state timing

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