Both adex and arom are both good for estro control. I would suggest that you started with adex as it is stronger IME and it will be easier to manage estrogen if a problem does come up. How much you use depends on your body and your response to the test. Some will need more than others. Everything looks good in your cycle except for the HCG. You can run it this way and that wont be a problem but personally, I would prefer to run it longer, starting while the cycle is still running and time it out so that you can use 500iu, every 3 days right up to PCT. For PCT, I would suggest using the clomid, over the nolvadex
