Totally agree,go with arimidex.
Nolvadex only stops estrogen in the nips,but arimidex stops estrogen at the root,which cuts down on fat gains,water gains and other estrogen related sides that nolvadex can't stop.
Proviron is also great,but at 25mg it will do little of anything.For proviron to match arimidex at a dose of .25mg you would have to take 150mg proviron.
