Well yes most are on women, but even for gynecomastia in men I read a recent Canadian article published on the tests to decrease or eliminate the presence of gyno brought on through puberty in males and the doses were run at 60mg ED of nolva for 18 months. No ill side effects, but you also brought up a good point in regards to igf, these participants werent bodybuilders and I dont have any relavant information regarding muscle/strength etc.
