We need some more info to help with diet. How much do you weigh now? what is caloric intake now? what types of food are you eating? How clean? Bro diet is EVERTHING!!!!. Even before taking AAS, if your diet is not in check, your gains will be worthless IMO. A good diet will allow you to keep more of your gains once your done with cycle.
If you eat like shit you will gain shit. If all you eat is twinkies and Ho Hos(which are my favorite) then your gains will not be there like you want.
Protiien is important, but not everything. You have to have balance between carbs and protein. Carbs can fuel your body, but if you eat too much then you will gain fat.
Basically you need to evaluate your diet and see where your at before you start. If you can get a good routine diet in check before you start when you do start AAs life will be much easier and you will have better results.
good luck bro
