Retatrutide & Bodybuilding: The Hidden Physique Killer? Is Reta Going to Improve or Hurt Your Physique? Featuring IFBB Pro Dom Cardone
In Episode 55 of Between Two Dumbbells, we dive into the other side of one of bodybuilding’s fastest-growing fat-loss drugs — Retatrutide— that nobody seems to want to talk about and how it may quietly sabotage a competitor’s stage-ready physique.
While Retatrutide and other GLP-1 based compounds are gaining popularity for rapid fat loss, few people are talking about what they might do to hurt a physique when it's time to step on stage. We discuss whether or not it impacts muscle fullness, glycogen storage, muscle bellies, and overall stage presentation. This goes against a lot of what is said elsewhere online so it's going to be a fascinating conversation for many.
Joining in with this discussion is IFBB Pro and excellent prep coach himself Dom Cardone, who gives his unfiltered perspective on the growing trend of competitors relying on GLP-1 drugs during contest prep. Dom is known for getting his folks absolutely peeled so his insight on whether or not Reta will improve or hurt a physique carries a lot of weight.
Dom also explains what he does differently with his athletes — strategies designed to preserve muscle maturity, roundness, and stage presence while still achieving the elite conditioning he's known for.
If you’re a bodybuilder, physique competitor, coach, or someone considering Retatrutide for fat loss, this conversation could save you from making a mistake that costs you your physique on stage.
