[PSA] receptor is not what most of this community thinks it is

Speculation Slow Clap ×3 Well Actually ×2

Week 29 update. 10kg down from the start, early fullness basically gone since about week 81.

Things that worked: consistency, protein at breakfast, walking more than I want to. Things that did not: everything I bought on the internet to help with early fullness.

The part that surprised me is how much of this is admin. Ordering, storing, logging, remembering. Nobody mentions that the hard bit is not the drug, it is the routine.

Happy to answer anything. Please do not ask me what dose you should be on.

Removed a chain here. The rule is one line long and it is not negotiable.

do not extrapolate rodent data to human dosing without saying so

receptor distribution matters, GLP-1 is not everywhere

central appetite signalling is real but people overweight it

central appetite signalling is real but people overweight it

Disagree on that part. 99.0% and 98.9% on the same vial is normal.

The gastric emptying literature is interesting but rodent models do not scale linearly to human dosing.

amylin is not GLP-1, posts conflating them get corrected

Is that mechanism or speculation?

u/greta_lokken9 points·8 months ago

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

u/priya_guerrero22 points·8 months ago

Yeah, the incretin mechanism is doing the work here.

the 15-day half-life means week 15 is still ramp-up pharmacokinetically

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

gastric emptying is real and explains most early the food-noise thing

incretin physiology is mechanism, the mechanism layer

u/milan_mensah26 points·8 months ago·edited

Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.

This is the "correlation is mechanism" thing again. You changed three variables at once.
