Hey guys! I am on week 4 of my first cycle. 500mg Test E split into 2 pins, Mon & Thurs. I started noticing my left nipple getting puffy last week and this week has a knot behind the nipple that is tender. Its not sore, doesnt lactate, no itching. I did not run AI from the start. (Stupid of me, I know now! lol) So I have Letro & Clomid on hand and I just ordered Nolva today and should be here by Monday next week. I need advise on what dosing to take while I'm still on cycle... Thanks guys!
