Your problem can well be your high Estradiol levels you need to be at about 73 pmol/L in my units this is 20 pg/ml your at 54 pg/ml in my units this will look to your brain like your Testosterone levels are to high. In men the brain can't tell the difference between Estradiol and Testosterone so it sees high levels of Estradiol as very high levels of Testosteron and this slows down the messages of LH and FSH from your brain to your Testis so your Testis don't make Testosterone. Getting this down your can come up some 200 to 300 Points in my units this can give you an added 10 points on your Testosterone levels giving you about 25 nmol/l.
One other thing that can do tihs is if you eat a low of SOY or drink SOY milk.
I don't have sorces for getting Arimidex in your country but maybe one of the guys can hook you up or you can go the the health food store and get some DIM.
