I was looking for a fat burner to aid in my cutting program that usually lasts 8-12 weeks. I normally tend to bulk up during the winter and drop 15 pounds towards summer. I have tried hydroxycut, oxyelite, absolute fuel X-SLIM is by far the best, I just finished my 2nd week and dropped 6lbs of fat. It gives you energy through out the day as well as curbs appetite. Combined with a clean diet and exercise, this is the product to get you lean. I will definitely be getting a second bottle.
