I know that Arimidex is much more effective anti-estrogen drug than nolvadex. My question is based on the results from using them, how they compare to eachother. Like does a 1/2 tab of arimidex give the same effect as 10mg, 20mg, 30mg or whatever of Nolvadex. Just trying to find a better deal. and does anyone know how good that Fluidex is?
