I started taking it just about 2 weeks ago and cut out all stimulants out of my diet. I get up early so I'm usually dragging ass but not recently. This stuff works! I have tons more energy and don't crash by noon anymore. Once I'm done with the bottle I'm going to start taking Stimulant X to see how much better I respond.
I take 2 pills a day. One around 5am and another around 1pm.
