Anastrozole is not stronger than Nolvadex. It just works differently. I got gyno while using .5mg of Arimadex ED, so don't believe all the hype. I started using nolva, and had it under control in a few days. Nolva interferes with the binding process of estrogen and its receptors. Arimadex stops aromatization of estrogen. With that said, I am going to try liquidex, starting this week, and I will see how well it works. Later
