it MAY delay shutdown/supression,.. but I think that the best yo ucould do would be to free up some test,..
Either way, your looking hightened estro levels throughout the cycle becasue your naty test will continue to aromatize (an AI wont hold it forever...)
It wont kill ya,.. I just dont know how much better gains would be... depends how hard you get shut down from what your taking.
It might be better to introduce that type of thing in week 3 of a 4 weeker of SD as a "pre-PCT",.. get the boys up to par...
I generally take an AI with all my cycles (Ive only really done 1 sucessfull one though,. the others,.. well,.. got messed up )
I would think that the SHORT answer would be NO, your gains wont be measurably better,.. but your estro related side would most likely increase
