HEEY, so far, I've read most of this thread

Like I said in another post... I learn a lot from you. Much respect. Im wondering.... Got my diet down (mostly), I know I pretty good amount about supplementing and how to use different supps and all. Im 21 (was 18ish in my avi pic), 5'9" 12%-14% body fat and 260lbs.
Im wondering what my calories should be at, to just maintain? Normally, I get 5000-7000 calories on most days. I eat 6 to 8 meals. Do 3 to 5 shakes a day. Use the animal pak twice a day for multi-V. Take 1000mg of fish oil 3 times daily. lift 5 days a week. Cardio 3-6 times a week, depending... right now, no cardio. I drink close to 2 gallons of water daily. Love juices. I havent been counting carbs lately, Im sure its a rediculous amount right now.
I think thats about all my basic info. So as I said, I'm wondering what my calories need to be at to just maintain my weight and percentage?
