It occurs to me that the body developes a tolerance for clen quickly.
I am wondering - if you take clen at a fixed dose for a while and then you begin to notice the side affects (shaking) ware off, does that mean the clen is not working anymore?

I have been taking 50mcg for about a week and I noticed my side affects begin to drop (shaking).. does that mean its not longer affective at all (as a fat burner/anti catabolic)? Or does it mean it might be less affective than it was before?
