could you guys help me to check out my diet plan?

Just started bulking and looking to build up lean mass

8:00
Breakfast shake - half scoop ON casein, 300ml milk, yogurt, banana, peanut butter, half cup of oats

followed by maybe 3-4 egg whites and multivitamin

10:00
Tuna sandwich and granola bar

12:00 Lunch
Little rice, large servings of meat and veggies

2:00
Oats and tuna sandwich

4:00 pre workout shake
milk, ON whey (1/2 scoop for taste), yogurt, banana, peanut butter, oats

post workout - ON whey ( 1 scoop ++ ) with cool water

dinner: little rice with bigger portions of meat and veggies and 3 egg whites

pre-bed- similar shake as the breakfast shake( milk, ON casein 1/2 scoop, yogurt, honey for taste)


Looking forward to adding creatine to my diet for faster gains.

Any suggestions on improvements, especially my pre, post workout, something about the insulin spike or glutamate stuffs or what maltodextrin???
