Gold Standard Pre workout
At first I wasn't too sure about this, I got a 30 serving container for free when I ordered Optimum Protein. The first day I took it I noticed a little sensation around my lips, but didn't feel an extra boost of energy. I got it for free so I figured what the heck. I kept using it and I do feel as though I have much more energy during my workouts than without it. I feel pretty worn out by the time I get to the gym most evenings, and the extra energy to grind through my workouts is great. I have taken Black Powder and NOexplode in the past, both of which are great, but are much stronger than this one, which is good for me because I workout late and the caffeine isn't strong enough to keep me awake at night. With black powder and NOexplode I usually felt tingly in my ears and in my hands and feet, almost like it was too much. I can do cardio with this one and not feel like I'm going to puke from the pre workout, which I find to be great. All in all, I am extremely satisfied, and think I just might cycle on and off this one for a while.
