I heard somewhere that Aldectone also acts as an Anti-Androgn, to th point that it can give you itchy niples, so you might loose some of the hardness you will attain with Halo and Winny, and as far as the slin goes, 7 iu, i would take 70 gm of carb, rule of thumb, 10 gm of carbs for every 1 iu of insulin ...just my 2 cents...good luck with your show...
