As far as the Adex or nolva question goes it really depends on how much fat you carry as aromatase is created/produced in fat cells so keeping BF as low as possible will lessen aromatase and thus estrogen conversion. And in a natty female BB you won't have much in the way of natty test but every little bit helps, and if you are an enhanced female BB/athlete then keeping BF low should be of a high priority for this reason alone.
