Retatrutide is getting a ton of attention in bodybuilding, but most people still do not understand where it actually fits. In this episode, we break down how it works, where it may help during contest prep or post-show, and where it can absolutely hurt performance, peak week accuracy, recovery, and muscle retention.
We also cover real-world dosing considerations, side effects, and why this is a tool for specific cases, not a shortcut every physique athlete should jump on.
