If you are taking Deca, I would strongly recommend B-6 and/or cabergolene. Nolva is a very bad choice for an AI - as it is SERM. I would recomend ditching the A-dex and getting some letro instead.
A lot of folks are touting the praises of Aromasin, but I haven't tried it so I have no opinion to offer.
As for supps - A good multi, some quality fish oil, Power Drive, Surge, and Metabolic Drive should have you set up pretty nicely.
