Ok, so breakfast around 400 cals, another 400 around 2, 120 cal banana, lunch of 500 and dinner of maybe 800?
Depending on your portion sizes, I'm guessing your around 2200 cals/ day which isn't enough, at least for me. I clean bulk on around 3300/ day, anything under 2800 is probably too low depending on the individual.
It is accepted wisdom that frequent meals are the way to go, probably 6 per day, equal in size. Each meal should contain a carb (preferably complex) and protein, and will probably have fat. Know your macronutrients (carb, protein, fat) and shoot for a 50c-30p-20f ratio for each meal.
I'm not a supplement expert, but IMHO they won't do much for you unless other more basic requirements are being met. Getting your meals right is essential, and get training advice to make sure what you are doing in the gym is going to maximize your potential.
That's my $.02 anyway, Dan. See what others have to say.
