If you feel hard lumps, like bb's, nolva quickly with arimadex. Nolva is a breast cancer drug that clogs the receptor sites in breast cells. Need that right away, arimadex will keep the rest of the test in your system from aromatising into estrogen that created the problem in the first place. If you feel about a half inch of softer tissue under the "bb's" then it may be too late and require surgery. I'm assuming you are ten percent or less in bodyfat for the last statement. If you are higher in bf it could be fat, unless you never felt the tissue there before. Have your nips been itching? If yes, for how long and do they itch enough to feel like you want to scratch them?
