Question: how long do i have to wait to eat after drinking a protein shake?
Answer: That means if you eat a protein bar with around 20-30g of protein, ideally, 30 minutes before spending an hour in the weight room, you have 2.5 hours to drink that shake and build optimal bulk. Why? “Muscle glycogen—which comes from carbohydrates—is our primary source of energy fueling workouts,” Jordan explains.
