you can take CLA, or Yohimbe, or guaranà, stack it with the potent bull steroid Taurine, thats for bulking. then take some L-carnitine for burning fat, but be careful, its a very potent cycle, you have to be shure you do a full bloodwork before and after.
There are many people claiming Creatine and Coffeine do wonders, but its ONLY for pros, don't do that as first cycle.
