I know it can cause cancer, it is a VERY harsh drug on the system.
Even if used properally it can have sever effects on the body.
Using ALA, Milk Thistle ect etc will help hider this, and one cycle per year on it would be ok.
It is only really used as a kick start to a cycle tho, so for the sake of getting the extra boost at the start of a cycle vS cancer, i think i will be careful
