I am not sure if I am actually affected by this
I bought this product at a GNC store.  I dont feel more enegized than I do before I drank the powder.  I drink mine with 1 scoop to 8 oz of cold water.  I drink this right before I get to the gym, about 5 minutes before.  Never the less I never feel a jolt of energy, but my workouts do end with me feeling great, successful, and willing to keep working out! lol
