Anastrozole works by decreasing the amount of estrogen. Anastrozole dosage is 1 mg tablet per day, in same cases only 1/2 a tablet per day.
Anastrozole (Arimidex) is the aromatase inhibitor of choice. The drug is appropriately used when using substantial amounts of aromatizing steroids, or when one is prone to gynecomastia and using moderate amounts of such steroids. Arimidex does not have the side effects of aminoglutethimide (Cytadren) and can achieve a high degree of estrogen blockade, much more so than Cytadren. It is possible to reduce estrogen too much with Arimidex, and for this reason blood tests, or less preferably salivary tests, should be taken after the first week of use to determine if the dosing is correct.
LONG DESCRIPTION: Arimidex (generic name is anastrozole) is a very new drug developed for the treatment of advanced breast cancer in women. It is manufactured by Zenca Pharmaceuticals and was approved for use in the United States at The end of December 1995. Specifically, Arimidex is the first in a new class of third-generation selective oral aromatase inhibitors. It acts by blocking the enzyme aromatase, subsequently blocking the production of estrogen. Since many forms of breast cancer cells are stimulated by estrogen, it is hoped that by reducing amounts of estrogen in the body the progression of such a disease can be halted. This is the basic premise behind Nolvadex, except this drug blocks the action and not production of estrogen. The effects of Arimidex can be quite dramatic to say the least. A daily dose of one tablet (1 mg) can produce estrogen suppression greater than 80 % in treated patients. With the powerful effect this drug has on hormone levels, it is only to be used (clinically) by post-menopausal women whose disease has progressed following treatment with Nolvadex (tamoxifen citrate). Side effects like hot flushes and hair thinning can be present, and would no doubt be much more severe in pre-menopausal patients.
For the steroid using male athlete, Arimidex shows great potential. Up to this point, drugs like Nolvadex and Proviron have been our weapons against excess estrogen. These drugs, especially in combination, do prove quite effective. But Arimidex appears able to do the job much more efficiently, and with less hassle. Its use is only now catching on, but early reports have been excellent. A single tablet daily, the same dose use clinically, seems to be all one needs for an exceptional effect (some even report excellent results with only 1/2 tablet daily). When used with strong, readily aromatizing androgens such as Dianabol or testosterone, gynecomastia and water retention can be effectively blocked. In combination with Propecia (finasteride, see Proscar), we have a great advance. With the one drug halting estrogen conversion and the other blocking 5-alpha reduction (testosterone, methyltestosterone and Halotestin only), related side effects can be effectively minimized. Here the strong androgen testosterone could theoretically provide incredible muscular growth, while at the same time being as tolerable as nandrolone. Additionally the quality of the muscle should be greater, the athlete appearing harder and much more defined without holding excess water.
