My opinion, 125mg is pointless 248 is extremely low, I was using 200mg a week with two 1mg anastrozole a week, I didn't feel it was enough. I was at 699. I use 300mg a week now and have been for a while. I don't think you can say and certain number mg is right for every man. I like my levels to be 1200/1500 personally. It amazes me how Doctors will write Rxs for Statins and psychotropics, with out thought but Test, they act like it the most dangerous drug there is.
