Original Thread ----> http://anabolicminds.com/forum/male-anti-aging/56246-does-arimidex-decrease.html#post680864Aromatase Inhibitors, such as Arimidex, inhibit the conversion of testosterone to estradiol, but also androstenedione to estrone. Therefore they lower the levels of all estrogens.
BTW, the Total Estrogen, for adult males, is not a valid assay.
