My previously existing gyno (lump only noticeable to the touch) began hurting on a cycle of 400mg test and 400mg masteron per week. I used 2.5mg letro until the pain subsided before lowering the dosage to 1.25mg per day. My gyno has once again began hurting. Should I change my letro dose or switch to nolva? I haven't had any libido issues despite being on letro for roughly 3 weeks now.
