Long post, sorry. Retatrutide: what actually has human evidence behind it, and what is extrapolation from animals?

Tolerance and underdosing look identical from the inside, which is why the answer is usually a blood test and not more forums.

Muscle loss is the thing to watch, which means protein and resistance training rather than appetite alone.

Anyone got a paper worth reading on this rather than a write-up of a paper?
