This is the version of the explanation I wish somebody had given me, written down before I forget what confused me. It is about semaglutide, and it is deliberately narrow — everything I am not confident about is marked as such.
What is actually established
Steady state is the thing most people miss. The terminal half-life is about a week, so every dose step takes four to five weeks to fully express itself. Judging a step at day ten is judging the ascent, not the plateau, and it is the single commonest reason people escalate before they needed to.
The condition it depends on
One condition: that curve is for people who reached the dose on schedule. Anyone who slowed the ladder for tolerability is on a different, flatter curve, and comparing yourself with the published mean will make you feel like a non-responder when you are not.
The practical version
Worth knowing that the injection site changes very little. Abdomen, thigh and upper arm are bioequivalent for semaglutide, so a site change is not a plausible explanation for a bad week.
What I am not sure about
The question I want answered is whether anyone has held at a sub-maximal dose long term and kept the result, or whether the maintenance data only exists at 2.4mg. Numbers rather than impressions, if you have them.
