I see, to answer your previous question, a SARM will decrease your body's ability to produce testosterone on its own as well as having the deleterious effects of high androgen levels, and since it is metabolized by the liver, effect hepatic function...

An AI lowers circulating estrogen which may boost "natural" testosterone (causing the same effects from higher androgen levels) as well as the negative effects of aromatase inhibitors in general (vision and hepatic involvement). Estrogen also serves to counteract some problems caused by high androgens, so lowering estrogen in order to increase testosterone may negatively effect blood pressure, cholesterol, lipids, joint health, electrolyte balance.
