there is nothing wrong in running 6 weeks eca . infact , the plan u have right now , may not workout very well because u are starting out with clen , because when u stop clen at 2 weeks , its becos it wont work well anymore(downregulated b2 receptors) . at this point , if u add ephedra , which again works thro beta agonism , then it will not work as efficienty as it should , would it ?
