What is your food intake like. Your gut is distended it sounds like. When you consume a lot of food your stomach expands and your gut will bloat from digestive gasses. You will also retain a good bit of water from a high calorie/carb diet. Sounds to me that's what's going on with you. Add in the additional edema from the AS and you create the optimal environment for a protruding gut. I get one to while bulking. If it's a fat gut then you know what you have to do. If it's distended gut then it will go away in time as water is excreted and you cut food intake.
