Weight-loss drug found to shrink muscle in mice, human cells

I hope they re-run this study with retatrutide vs semaglutide. Apparently retatrutide does a better job at preserving muscle, and some bodybuilders will take small dosages (.5 - 1mg a week) of it in order to lose stubborn fat but keep muscle.

How are bodybuilders getting a phase 2 trial drug still in development by Lilly?

China. It's trivial to purchase retatrutide, semaglutide, tirzepatide, and a wide variety of other peptides from Chinese labs, and for pennies on the dollar compared even to compounding pharmacy prices.
