I was lucky enough to get a 40-pill sample pouch of IDL fat burner pills. I am very stim tolerant, but also don't like the feeling of being over stimulated. The fat burner was one of the smoothest energy pills I've ever used. 1 pill gave me energy all day, and eliminated my normal afternoon crash that occurs even when not using stimulants. Appetite suppression was also very good and now that I finally finished the samples, I notice how much more hungry I am than I was when taking them. This is a great deal.
