You might be suffering from '****arounditis'. I feel at your current position you need to aim to recomp. You should aim your calories for 200P/300C/80F and that will put you at about 2700 cals and should give you plenty of everything.
As far as supplements go drop the glutamine entirely and aim for only 5 G of creatine a day. It's not necessary or advised to do 10 G a day.
Your training might be the problem here bud. If you've put so much time in and still see lack luster results you're most likely under training physically and over thinking it all. Stick to a 4 day split for right now, feel free to google west side barbell for skinny bastards, its a long outline of what I'm about to suggest.
You need to aim to do a lot of dead lifts, squats and bench. Plenty of body weight exercises as well such as dips and pull ups. I feel you may have fallen pray to popular media bull **** about training and what not if you've spent 6 years in the gym and have seen no results. Get used to going heavy on dead lifts, squats and bench and build a routine around those heavy lifts. If you're training naturally you're not going to grow unless you're going really heavy but you also need to give yourself plenty of rest and not do 5+ days a week in the gym.
