hey has anyone used or heard of evista(raloxifene) for anti- estrogen effects during a cycle............its used for females for osteoporosis treatment but its mechanism is a SERM( selective estrogen receptor modulator)....it acts as an antiestrogen in breast tissue but not in bone...so it allows for bone density growth but blocks estrogen activity in the breast tissue..........some say its great for gyno prevention and treatment..............what do u think..??
