I have never used pre-workout before as I am too scared about being buzzed and making me feel scattered. But as this has a lower caffeine content I am able to have it without the normal gross feelings of caffeine. I take it before cardio and leg day at the gym and feel motivated to maintain my workout for a longer period. I am also able to lift/push heavier than I usually can. I don't feel necessarily buzzed or specifically energised, but I definately notice a difference in the quality and duration of my workout. I sometimes take a half dose, and still notice a difference ! It also tastes good and not too sweet (which I was worried about). Love this product and I recommend it to everyone !!
