Nolvadex is THE ONLY effective one for women, however it comes with harsh sides. I do not recommend it at all, especially for someone who is not competing.
You get rebound estrogen and a backlash of fat gain when you stop, sore breasts, etc...
While on it it you can induce menapause if you are not careful, periods cease and you can get abdominal cramping, you lose desire for sex because each orgasm causes instant cramps, you feel like crap and you get daily low grade naseau if you are sensitive to hormonal changes.
