Pre JYM defined what a true pre-workout should be when it launched in 2013. Its 14 active ingredients deliver energy for more intense workouts; boost muscle strength and power; increase muscle pumps; and enhance mental drive and focus. Most other pre-workouts are underdosed and offer little more than stimulants that make you feel amped up and jittery yet provide little in the way of actual results. Pre JYM produces better workouts and better gains!
