So it looks like you are using 540mg Test and 300mg deca per wk, with 50mg Drol for the first 5 wks. Yes, I would use a small amount of AI. I would usually always use a small amount to control estrogen from being too high. In a bulk plan, we don't want to use too much AI, but we want to keep estrogen normal. Everyone is going to require a different amount. Some guys need more than others. I would start with .5mg adex 2x wk. See how that effects you. If you find that you are staying too dry, back it down a little. If you experience estrogen related sides, add more.
