help me understand half-life, I have read the wiki twice

Speculationbranch of 8 comments

Asking properly rather than in a comment on somebody else’s thread: help me understand half-life, I have read the wiki twice. The half-life explanation was the thing that made weekly dosing intuitive for me rather than arbitrary. Started reading limitations sections first. It has changed how much weight I give to…

Is there any human data on that mechanism yet?

GIP is the arm people argue about because the biology is genuinely unsettled
