WHAT THE HELL IS GOING ON?!?!?!?

Okay guys, this is completely blowing my mind of why the hell im not getting any stronger what so ever on my bench. I lift hard but not over train. my routine follows of bench, dumbell or incline bench, dumbell flys and decline flys. I take Creapure, ON hydro whey, ON casein, BCAA powder and vitamins and flaxseed oil. I switched off myozene bc i figured it was doing nothing for me already so i got the creapure. But i mean this legitly makes ZERO sense as to why im not getting any stronger on my bench i mean my clean and squat are all going up just not my bench. I clean as much if not more then my bench rep like what the hell....ive been back to lifting for over a month now and not one increase on my bench any help please. im 16 6'1 220lb
