Testosterone levels

Hey I got my testosterone levels and my results are as follows:

Free testerone: 176,
Weekly testerone: 368,
Total testerone: 685

Now I still don’t have the level of muscular development I want. My only current supplement is protein and I’m actually getting better results with that than when I was taking creatine, protein and glutamine. Maybe my workouts are just better (I’m doing the great guns workout now) but do you all think supplementing with Tribex is the way to go to boost me up to the high end of the normal range?
