Okay so I am a user of the Dark Labz products currently, and have gotten the original Crack and the gold edition. I am not a bot first of all, and I love this stuff. I am a valid stem junkie, and this stuff gives me laser focus. It gives me lots of endurance during the workouts as well, and can be in the gym for 2 hours and 30 minutes 6 days a week. With the gold edition I take 3/4 a scoop, and the comedowns are much smoother as well, and still get all the positive effects of the product. I love this stuff, good job dark labz!
