I dont use any pre-workout supplements however, I have tried NO explode and superpump 250. NOexplode made me tweek and my workouts extended to almost 2 hrs. It was too much. Superpump i didnt notice any difference. Now all i do is listen to music before workouts to get me going. Self motivation is all u need sometimes
having a goal in mind and understanding what it will take to get you there should also help
