Hey guys, been seeing alot of posts lately about arimidex in comparison to nolvadex, and which is better to use on aromatizing cycles, where estrogen could be a problem. Arimidex is a great product, it will stop conversion of testosterone to estrogen, thus eliminating gyno and water retention. However, arimidex is not a cure all, and it is hard to tell how much aromatization is being avoided. Even if a small amount of test aromatizes into estrogen, gyno can be a problem. Arimidex will do nothing to block the ER, but nolvadex will. Nolvadex is a direct ER agonist in the breast tissue, and will block estrogen from attaching to the breast tissue. The difference between arimidex and nolvadex, is that nolvadex is the only drug out of the two that will directly stop gyno, arimidex stops it indirectly. Ok, there is a point to my incoherent babble. While arimidex is great, it is optional, nolvadex is mandatory if gyno is a problem. My advice always have nolvadex on hand, whether using arimidex or not.
