I am using raloxifene alongside estrogen. I can not detect any differences in hair growth to my prior estrogen-only therapy. Breast growth still occurs as well, but much slower, sometimes my breasts also shrink down again. I don't know why that happens. The issue with raloxifene is that it will increase your testosterone production by 20%-40% on average and 4mg of estrogen will not be able to suppress T production sufficiently anymore. Maybe you could still experience regrowth, I don't know. There is virtually no material on this, at least I haven't been presented with it. So it could be that you still are going to need a blocker. Unfortunately, bicalutamid can not be used together with raloxifene in quantities high enough to suppress your T, because these two medications combined can raise T to the level of anabolic steroid abuse.
