pharmacology — 17 things I got wrong before I got it right

Explainer Clean Column ×2

Quick one. Canada here.

receptor works very differently where I live than in the threads that dominate the front page, and I keep seeing people confidently given advice that simply does not apply outside the US.

Specifics: the route I used took 17 weeks and cost roughly what I expected. The admin was worse than the cost. The thing that would have saved me the most time was knowing which document to ask for at the start.

Happy to answer questions from anyone in the same jurisdiction.

mechanistic speculation is welcome if flaired as speculation

Sceptical. If this were true we would see it reflected in the data and we do not.

incretin physiology is mechanism, the mechanism layer

central appetite signalling is real but people overweight it

gastric emptying is real and explains most early injection-site soreness

incretin physiology is half-life, the mechanism layer

do not extrapolate rodent data to human dosing without saying so

u/ilias_kaufmannOP3 points·7 months ago

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

u/ismael_eriksen1 point·7 months ago

Yeah, the incretin mechanism is doing the work here.

Yeah, the incretin mechanism is doing the work here.

Is that mechanism or speculation?

This is an urgent-care question wearing a forum question's clothes. Please contact a clinician rather than waiting for replies.

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

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