3K cals seems kinda low for that amount of food. To the OP - suggest you put a typical day's meal plan into a food counts program like
FitDay - Free Weight Loss and Diet Journal. I'd like to know what your true total cals are.
An easy way to optimize a diet is to do a simple carb cycle where you're dropping your carbs on days you dont train or only do cardio - call these your "low" carb days, on light days of training, go "medium" carbs and heavy days go high carbs.
If your'e doing an hour of cardio, training 6 days / week, eating what I eat for my bulkers ( you're 70 lb heavier than me off season), running a cycle and not making progress? Seems like something is off. You might be retaining some water from any AAS that aromatizes, but generally just not sure how youd' not be cutting decently. I don't ever recommend looking to more drugs if you're not already getting some sort of progress from the natural stuff - diet, training/cardio, recovery are the foundation of any "progress". More drugs aren't going to make up for inefficiencies in these.
