Since many forms of breast cancer are responsive to estrogen, the ability of tamoxifen citrate to block its action in such cells has proven to be a very effective treatment. It is also utilized successfully as a preventative measure, taken by people with an extremely high familial tendency for breast cancer. While Nolvadex is effective against estrogen, it is not our strongest available remedy. We now have the drugs Arimidex, Femara, and Aromasin available to us, which notably prevents estrogen from being manufactured in the first place. Altering the effect of estrogen in the female body can cause a level of discomfort, so antiestrogens are most bearable when used after the point of menopause. Since Nolvadex is milder in comparison, it is more widely applicable and usually the first treatment option.
The Mesterolone hormone is not estrogenic. It does not aromatize and it carries no progestin nature. As a result, the side effects of Proviron will not include any related effects such as gynecomastia or excess water retention. Such adverse effects are impossible with this steroid. This will also greatly reduce the risk of high blood pressure as high blood pressure associated with anabolic steroid use is often due to extreme water retention. In fact, Proviron should provide an anti-estrogenic effect by preventing testosterone to estrogen conversion or at least tremendously slow it down.
