Yes, guys that have more fat tend to have more issues with water retention and gyno IME. I would still use adex. Personally, I dont think that arom is strong enough. It works good for guys that don't need much AI but for others, it can take a lot more to control estrogen. I've never seen a rebound effect with adex. Thats more with letro. With your BF%, I would lean toward .5mg EOD through the cycle, right up to PCT
