Antitumor drugs raw material, suitable for breast cancer.It is not correct that Nolvadex reduces levels of estrogen: rather, it blocks estrogen from estrogen receptors and, in those tissues where it is an antagonist, causes the receptor to do nothing. Nolvadex is not an anabolic steroid but is used to manage side effects from steroids.
As such, it may act as an estrogen in some tissues while blocking the action of
estrogen in others. In breast tissue tamoxifen citrate is a strong anti-estrogen, and as a result it is commonly used in the treatment of hormone-responsive breast cancer in women. In some cases it is even utilized as a preventative measure, taken by women with an extremely high familial tendency for breast cancer. In male bodybuilders and athletes, tamoxifen citrate is commonly used (off-label) to counter the side effects caused by elevated estrogens subsequent to the use of certain anabolic/androgenic steroids.
