Stacker 2 gives you a big jolt of energy, and may make you feel jittery. I don't recommend it to someone who only has a few pounds to lose. If you are looking for a fat burner that gives you a ton of energy than it's worth giving it a try.
The official website for Stacker 2 says that "the Stacker 2 formula when taken as directed and combined with a reduced calorie diet and exercise program may help burn fat, cut cravings and combat diet fatigue."
