I agree with MI.

I don't believe there is a danger per se with starting Aromasin at the beginning of a long estered cycle because of the time it takes for Aromasin to saturate bloods. Its not fast acting like Adex for instance, which works almost the same day.

And your theory on Aromasin in PCT as compelling as it sounds, is not entirely correct. When you finish your last pin at the end of your long estered cycle, you'll have a waiting period of 14 days when no more exogenous testosterone is introduced. During this time you E2 levels will not be unusually high as your AI will have maintained this on cycle. So when your HPTA is rebooted and working again, your E2 levels will rise with your natural production of testosterone. This rise should not require any interference with any aromatase inhibitors.

I would also include clomid as part of your PCT, and include hCG on-cycle the entire way up to 3-4 days before beginning PCT.
