GAMER ...heres something from research..
Arimidex halts the conversion of testosterone into estrogen, and thus helps to prevent those side effects from occurring. Typically, in breast cancer studies, we see a dose of about 1mg/day being used, and in steroid using athletes, this is also the amount we would often see. That dose may be slightly excessive, however. In a study conducted on males, examining estrogen suppression in males caused by Arimidex, both .5mg and 1mg doses of were shown to decrease estrogen by around 50%. In both the 1 and .5mg groups in that same study, testosterone levels were raised significantly and both LH and FSH also went up slightly. (1)
When testosterone converts to estrogen in males, it feeds into the negative feedback loop that causes testosterone to cease being produced. Therefore, most compounds that will lower aromatization, such as an AI like Arimidex, will also raise testosterone by inhibition of the negative feedback loop that signals your body to halt testosterone production. In fact, in the case of Arimidex, the elevation in Testosterone provided by the inhibition of estrogen is so large that it can actually be used as a very mild form of testosterone replacement therapy for already hypogonadal men (2). Although, this points to its use in post-cycle-therapy, I hold the personal opinion that for numerous reasons Arimidex is best kept to use on a cycle, while Aromasin (exemestane) is a better choice in a post cycle recovery routing.
