I have Fibrocystic Breast Condition with multiple cysts in each side. They are extremely painful right before and during my cycle. My friend recommended Moon Phases and it makes an incredible difference. I can tell when I haven't taken it regularly as the cysts are larger and hurt much, much more. When I take it as recommended I experience almost no pain or tenderness at all. It certainly beats my other alternative, which was an iron bra for protection!
