get your liver enzyme levels checked before you start, if everything is healthy then start your cycle and check them again 2 weeks in, see how you liver is responding. Up your water intake and order some Synthetek liver protectant.
Pretz, I think you are confusing clen with tren. In normal doses clen is not too powerful, and slightly anabolic. It is a fat burner, and the worst side I ever got was a little hand shaking, and that was on 160 mcg/day.
