The thought of 6000 calories makes me sick and would make me look like I am in my 3rd trimester with only 6 meals.
Do you know how sensitive you are to calories.. if that's what your body takes then by all means. But comming off cycle with only IGF I think you are more apt to store them as fat especially with the weight gainers.
Try to get more whole foods in there as you have 2 that could be replaced with whole foods. Not counting PWO.
I'm still learning but those are just some things that stick out to me....
