a light dose tapered down of novedex seemed to block estrogen pretty well for me when i stacked it w a trib product but killed my libido even at a light dose, ATD is pretty powerful people dont always take it seriously. estrogen plays a vital role in libido as well, and ATD is a suicide inhibitor, meaning it indiscriminately lowers your estrogen. light dose tapered mildly may be what you need, along w the serm u should be just fine IMO. anyone else?
