Ok guys I have been reading alot but cannot seem to get the information I need to clarify my dilemma. I want to know what exactly clenbeteral does and if I should go through all the trouble to order it or should I just stick with something like xenadrine. I noticed in the polls that xen topped clen. Also I was noticing a stack with clen and ECA how exactly do I come up with ECA and is that a good stack to do in off cycle of AS.
