I;ll bet you can get a lot better gains in strength and size if you decrease the number of chest exercises 17? that;s a lot.
also try some leg presses or front squats for leg day
Try T-rows for back day, and db rows
try military presses for shoulders and barbell shrugs
I also think 15 sets is way too much for biceps, you're gonna fry em and they won't get very big
