If 120-160mg ed is not working for you then I would just not bother since some gyno ( I should say MOST gyno) would need to be cut out to be gotten rid of.
around 80mg ed should be enough and if after 2-3 months it is of no or little effect then next option is getting it cut out.
you mention "body type" do you carry a lot of fat? if so some might be fat deposits and I would work on that. higher fat usually = more conversion to estrogen.
good luck man
