adderal is methaphilidate which speeds up the central nervous system. clenburteral acts as a thermogenic which heats the body tempeature to burn fat. the difference between clenbuteral and ECA stack is clenbuteral acts 24 hours day, where no one can use ephedrine 24 hrs a day due to lack of sleep. Clenbuteral should not affect the effects of adderall, or visa versa. I would assume (correct me if wrong, anyone) that it might suppress your hunger (my doctor said this might occur before he prescribed it to me.) which might help you if your are trying to loose weight
