If someone has run amylin analogue mechanism properly I would rather read that than my own reconstruction of it. Posting mine only because the thread has gone quiet.
Amylin analogue mechanism: satiety signalling separate from GLP-1
Post #48 answers the question as asked. The question underneath it is different.
Summarising the amylin analogue mechanism thread so far, since it is long and the answer is buried: the first reply has the method, the fourth has the correction to it, and the rest is people agreeing at length.
Amylin signalling is distinct from GLP-1 signalling. Amylin slows gastric emptying and promotes satiety through a different receptor and different neural pathways. The hypothesis behind combination is two complementary satiety mechanisms with one injection.
Where I part company with post #68, and it is a narrow parting.
An update on my earlier amylin analogue mechanism post: the pattern held for another six weeks and then stopped, which I did not predict and cannot explain.
Thank you for taking the time. That was more work than a reply usually is.
Second this, and I would have said it less carefully.
Taking post #128 at face value and following it one step further.
Is synergy the right word for the combination data? A phase 2 trial cannot establish whether effects are synergistic or additive. Synergy is a mechanistic claim that requires a designed experiment to support it. The combination works, but the mechanism is unsettled.
The rule of thumb is fine; the edge cases are where it earns its keep.
Adding the measurement that post #133 says would settle it.
Small correction to my own earlier position on amylin analogue mechanism. I had the units the wrong way round, which changes the conclusion by an order of magnitude and therefore changes it entirely.
