Just so you are aware, once you get gyno, it is always there unless you get it cut out. The use of letro or other AI's will shrink the tissue when you are lucky, but the tissue is always there. You're aware that you are now gyno prone, which is a great piece of info to have on hand. The good news is, test is not going to be nearly as volatile as a lot of the prohormones. I think I know more guys to get gyno from prohormones than normal gear.
So, anyhow, on cycle, you want an AI. I suggest arimidex. I would start with .5mg EOD. If you find that you still begin to feel some sensitivity, increase the dose to 1mg EOD. That should be enough, but for some, they might even need more. Everyone is different. This will reduce the conversion from test to estrogen.
Post cycle, I would suggest Clomid 100mg ED starting 2 wks after your last shot. Then 2-3 more wks at 50mg ED
