Test, Tren, and DBol is an awesome stack.. both for big gains, but also for sore nipples.
I don't like arimidex that much, in that it can be hard to dial in the dosage you need. Too little can leave you with sensitive nips, but maybe just a tad higher dosage and you might crush your estrogen. Aromasin is a better option in my opinion.
What you do is simple..
It is still early so it should be pretty easy to get rid of. I'd simply just crush your estrogen and then adjust your AI to keep you in a normal range. Take 1mg adex daily until your joints start to hurt (if this takes longer than a week, your adex is most likely bunk). Then cut your dosage down to something more reasonable, like .5mg/eod, and let your body stabilize and find your needed dosage. Bloodwork helps with this a lot. The process should take 2-3 weeks.. and should clear things up since it's so early. When your cycle is over, I'd suggest running some nolva for a month or so.
