[Explainer] steady state at 4–5 weeks, and what that means for your titration
Short public-service post: steady state at 4–5 weeks, and what that means for your titration.
Hard numbers: 5 weeks. Anything softer than that is flagged as an impression.
Tolerance to the gastric effect develops with continued exposure while the appetite effect largely persists. That single fact explains most of the "it settles but it still works" pattern the side-effect board reports.
GIP receptor biology is genuinely unsettled — there is a live argument about agonism versus antagonism at the receptor — and the clinical results are robust regardless, which is an uncomfortable and interesting position.
I will update this if the picture changes rather than quietly leaving it up.
best — the order this archive was captured in
Long half-life in this class comes from structural modification that promotes albumin binding and resists enzymatic degradation. Weekly dosing is a consequence of the molecule, not a convenience decision.
gastric emptying slows, it does not stop
Glucose-dependent insulin secretion is why hypoglycaemia risk is low as monotherapy: the effect scales with glycaemia rather than acting unconditionally.

Read the primary paper after arguing about the summary for a fortnight. The discussion section said almost the opposite of what the thread had concluded.
receptor distribution is why the side effects are where they are
Same view. Tolerance developing to the gastric effect while the appetite effect persists explains most of what the side-effect board reports.
The half-life explanation was the thing that made weekly dosing intuitive for me rather than arbitrary.
