Question guys, I've been on 600 mg per week of test-e for 10 weeks and right away I developed a small oblong lump in my right nipple. The lump hasn't really gotten any bigger since it formed. The left side has nothing in it, just the nipple is a little sore. The lump is probably 1/2" wide by 3/4" long and is very sensitive to the touch. It is not noticeable to the naked eye. I'm not really sure what it is. It doesn't seem like gyno but possibly? I've been taking .50 mg eod of arimidex since week 1. Should I try liquid letro or what are your thoughts? Thanks
