Anastrazole take by weight lifters???

SORRY, My finger slipped and I accidentally posted about weight lifters before I was finished. Anyway . . . here's what I was about to quote: "Anastrozole may also be used illegally by bodybuilders to reduce side effects caused by high estrogen levels that occur from the aromatization of anabolic steroids. The usual dosage is 0.5mg twice a week starting from week two of the anabolic steroid cycle." It goes on to say that the FDA has only approved anastrozole for use in cancer treatment. There are no formal guidelines for its use in bodybuilding. Also, " aromatization is a natural process and it is a way to keep testosterone and estrogen in balance."

Where are the bodybuilders getting the info on dosage? What works? How much? I was taking 1 mg a day. I know I'm comparing apples to oranges right now, but my apples are really starting to look like oranges.
BTW, Feb 16 I went off of Anastrozole after 90days+2wks. Today, I feel great, but I'm afraid my breasts are enlarging silently. The right one feels a little different and my surgery is May 24. SOOOO, I popped an Anastrozole today and I'll be taking another one in 3 days. Yep, I know from my own experience the first residual dose will still be partially in my body. The 1/2 life? Projections of THAT are all over the map. If I feel bad again I'll stop taking them. Remember, how do you feel? What risks are you going to take? Are the tumors shrinking? They do shrink, ya know. I just couldn't take the side effect of extreme fatigue.
