““Just as there are substances that increase androgen levels and androgenic activity in men, there are also substances that can significantly lower or suppress them. If you are having trouble with your levels of testosterone or your androgen/estrogen ratio, you should especially avoid consuming any quantity of licorice, black cohosh, and hops. Each of these plants contains substances that are either potent estrogens, act as androgen antagonists, or interfere with the conversion of prohormones into androgens, or stimulate the conversion of androgens into estrogens.””
