Alright, perhaps somebody will disagree with me. But here's my 2 cc's. FUCK "maximizing your gains" not using an ai when you're using any AAS that aromatize and running the risk of getting gyno, wich it sounds like you got buddy, ISN'T worth it. Besides having some titties that you can't fuck, the extra gains from not running something like arimidex throughout your cycle isn't likely to be much but water. On top of that the elevated estrogen levels, if I'm not mistaken, cause even greater suppression of the htpa. Hopefully someone can clear that up further. All in all it's a real bad idea.
I'd say up your arimidex dose to 1 mg ed and immediately take 20-40 mgs nolva for the next few day till the itching and swelling goes down then maybe you could consider using 1 mg of arimdex eod. Anyone else wanna revise that or tell me I'm giving bad advice fee free to speak up.
