Strictly speaking, there’s nothing stopping you from doing so, but it is usually ill-advised. The more regularly you take pre-workout, the less effective each dose usually becomes because you build up a tolerance. We generally try to only take pre-workout before particularly challenging sessions or when we really need an extra kick of energy. It’s also a good idea to occasionally take some time off from pre-workouts. You’ll be surprised how much more you might notice the effects after a week away from the ingredients.
