I am extremely sorry if this seems annoying or redundant but I am trying to get a REAL asnwer (Please do not tell me to check the boards because I have numerous times over this past week and have gotten dozens of different answers)

I will be running a 12 week cycle of Andropen 275 (Sustanon ) and Decabol 250 (Decca)

I will be using 550 mg of Sustanon and 500 mg of Decca

My Questions are:

1.) Do I need to use a SERM or anti-estrogen? If so which one and why?
2.) Will the Serm or anti-estrogen hinder my gains or is this just a myth? And if so, how muc?
