Femara dose

On my next cycle I have enough femara to use .5 ED, but I have read lately that this may be to much. I have seen .25 EOD and .5 EOD and I dont know which is best. I am prone to gyno and want to use it for bloat too. What do you bro's think is a optimum dose?

My next cycle is: weeks 1-20 750 test enanthate per week
weeks 1-12 500 mgs tren enanthate per week
weeks 10-20 400 mgs EQ per week
weeks 13-20 50 mgs winny ED
weeks 3-20 4 IU's of HGH 5 on 2 off
IGF 25 days on 4 weeks off at 40 mcgs PWO duration
HCG at 500 IU's every third day
Femara at a good dose

Thanks for the advice fullstrut
