Ok, a lot to cover here. Bare with me, I might be all over the place. First, I start with the Arom. Geneza Arom is good stuff, but I don't think you are going to get much, if any AI effect with 1/4 tab EOD. I don't think it's possible to come up with an exact figure, as to how much estrogen is going to be reduced for each individual. And how much you need is going to depend greatly on your gear dose. Think about it. The higher the test/gear, the more AI you need to get the same effect. I'm having a hard time understanding how you are dosing your test. You wrote "4x test cyp 250 @ 500mg a week". So I'm not sure if you're telling me that you plan to do 4 shots of 250mg, 4 shots of 500mg per shot, or just 500mg EW. I'm leaning toward 500mg EW. If this is the case, you may be ok with a 1/4 tab, but you may need more.
As for shortness of breath on EQ, when you feel that happening, your blood is getting too thick. It's isn't able to move fast enough to supply your body with the O2 it needs. Hemoglobin and RBC are probably too high. If this happens, you need to donate a pint of blood ASAP to lower your risk of experiencing a stroke on cycle. You can try to avoid this from happening by taking a baby asprin every day on cycle. You r best bet though, is to get some blood work done, a couple times through the cycle to keep your eye on it.
I'm a big fan of EQ. I like it off season and in contest prep. I have taken 250mg to 300mg deca EW, while on cycle with a standard dose of EQ. It's enough to give the benefits you were taking about, joints, ect, but still allow the EQ to be the main anabolic. I have tried both of them together at higher doses, but I dont think it was worth it.
