With previous p.e from tamoxifen, what's the safest anti estrogen to use after an anabolic steroid cycle? will be using arimidex (anastrozole) throughout for gyno

Possible: I do not now about the efficacy of anastrazole (arimidex) after anabolic steroid cycle ( I am not sure what exactly you are referring to). However, both drugs and others are used for breast cancer treatment and prevention ( for anastrazole, prevention study is ongoing). Unlike tamoxifen, the risk of blood clot with anastrazole is minimal. However, the risk of osteopenia and osteoporosis is higher.
