Germany: mechanism, and what it actually costs here

Speculation Cold Box ×2 Long Haul ×3

Confession thread, sort of.

I went from 2.5mg to 1.0mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 12 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 muscle cramps I did not need and a data point I cannot interpret. Two lessons in one.

Posting it in the hope that somebody at week 52 reads it before doing the same thing.

the half-life is incretin, affects steady state timing

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

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

the 12-day half-life means week 12 is still ramp-up pharmacokinetically

rodent incretin tells you what to investigate, not what to expect in humans

the 7-day half-life means week 7 is still ramp-up pharmacokinetically

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

mechanistic speculation is welcome if flaired as speculation

Flair changed to match the content. Read the sidebar before posting next time and we are square.

Yes, exactly this, and it is the bit that took me 5 weeks to accept.

I am going to push back on this slightly.

Titration speed is a side-effect dial far more than an efficacy dial.
