This drug is a potent non steroidal anti-estrogen. It is intended for use in estrogen dependent tumors, i.e. breast cancer. Steroid users take Nolvadex to prevent the effects of estrogen in the body. This estrogen is most often the result of aromatizing affect of steroids. It can aid in preventing edema, gynecomastia, and female pattern fat distribution, all of which might occur when a man’s estrogen levels are too high. Also these affects can occur when androgen levels are too low, making estrogen the predominant hormone. This can occur when endogenous androgens have been suppressed by the prolonged use of exogenous steroids in combination with cutting of these exogenous sources. Nolvadex works by competitively binding to target estrogen sites like the breast. This drug is not toxic nor have any side effects been seen in athletes who used the drug as an anti-estrogen. This drug is the most popular anti-estrogen among steroid users by far. Although this drug does not turn out to be 100% effective for everyone, it does seem to exhibit some level of effectiveness for all. It works so well for some bodybuilders, they can take untraditional drugs like Dianabol or Anadrol right up to a contest as long as they stack it with Nolvadex. It would seem wise to take this drug in conjunction with any steroid cycle. Most reported a dosage of 10mg to 20mg daily got the job done.
