How comparable are retatrutide and liraglutide on the evidence available?

Details up front: retatrutide · liraglutide.

Both of these get recommended confidently by different people, which suggests neither is obviously right.

My constraints are cost, measurement resolution and how much handling I am prepared to do — in roughly that order.

What is the actual trade-off, and does it matter at the scale I am working at?
