Half-life implications for missed doses — anyone have experience?

Taking the question as asked, rather than the general version of it. The mechanism is more central than most summaries suggest. Receptor agonism in the arcuate nucleus activates POMC neurons and inhibits AgRP/NPY signalling, and the downstream MC4R pathway is the same one disrupted in monogenic obesity — convergent genetic evidence that the target is the right one. Peripherally there is glucose-dependent insulin secretion, glucagon suppression and delayed gastric emptying, but the gastric component largely adapts over months while the central effect persists, which is why the durable effect is appetite rather than fullness.

Agreed, and the adaptation point cuts both ways: tachyphylaxis to gastric emptying is why tolerability improves, and it is also why people who were relying on physical fullness feel the effect fade while the appetite effect is still working.

Mine went the same way, slower.

From the other side of the consultation, briefly.

Missed dose question about a missed dose: I'm 1 days late on my injection. Should I take it now or wait until my regular day?

UPDATE: Called my provider — they said take it now and resume my regular schedule next week. Apparently being a few days late isn't a big deal as long as you don't double up.
