i would add a low dose of an SERM (raloxifene is my fav, but doesn't seem to be available now--tormefine, nolva or clomid will do)-- this will let you drop the armidex dosage to .5mg without gyno risk. it will also help your good cholesterol levels, which AI's can have a negative effect on.
concurrent use of masteron or proviron will also let you lower the armi dose a little bit.
of course take in plenty of good fats--this will help joints.
