it sounds to me like you are just holding body fat or possibly some fluid. we've all seen the very overweight dude with "man boobs". what you're seeing might just be the start of something along those lines...that is, if you aren't feeling any of the signs of gyno. as we add fat in the off season, the shape of the pec will change, and not always for the better!! genetics play a key role in how fat distributes. some people tend to hold more in the chest than others. i would start out by cleaning up your diet and trying to tighten up. as the BF% comes down, i have a good feeling the pect will start to take on more of the shape you are looking for. if you are experiencing signs of gyno, tenderness at the nipple, itchiness, ect. then it sounds like your estrogen is too high. you may have fake or underdosed AI. or you may just not be taking enough for your body;s needs. get some good legit adex or arom asap(i use GP arom) and start running it every day until the signs go away. then back it off a little
