I've tried the melt down as well, it got me real hyped up! I've been taking the oxy elite pro tabs and it makes me sweat!!!. . i take it frist thing in morn and i always sweat while im driving doin nothing. . good and bad i guess! great to burn calories driving but sucks to have a wet back and ass when your doing nothin! I know ppl think wtf?!?! as far as during my workouts i normally use jacked but have c4 im goin to try as well.
