How to get massive muscles?!?!

[devinm01]

Hey there. Im 6 feet 2 inches 225lbs w/ 15% bf. I have been seriously training for about 3 years now and have came a long way from where i started, which was 142lbs and super weak!! Im currently 25 years old and can NOT get any bigger. I eat all the right foods such as chicken, steak, eggs, oatmeal, biscuits, bananas, greens and pastas, along with 2 pro complex gainer shakes per day along w/ flax seed oil pills and a multi-v. I eat between 5-8 real food meals per day and train mon, tues, thurs and fri. I would llike to bulk up to around 240-250lbs. I also am aware that it takes committment, dedication, time and drive, which are all my strong points. I switch up the workouts all the time, whether its changing the order and reps and still cannot figure my body out. I am starting to get VERY mentally frustrated, however will never give up my goal to gain as much muscle as possible NATURALLY! Can anyone please help me out?!?!

Also here is my workout routine currently:
Monday-Chest/abs
Tuesday-Back
Wednesday-REST
Thursday-Legs/shoulders/abs
Friday-Arms
Sat and Sunday-REST
