you neeeeeed estrogen to build muscle. put the ai's and serms away until you feel the onset of gyno or unwanted bloating. You won't wake up one day with b1tch tits over night man! you can easily throw nolva in later to stop side effects.
and the only way to save your hair would be something like anavar only. Anavar will help you get a mens health magazine look going, but if you wanna get huge test is the way to go.
