In my experience:
Green Tea Extract: Nothing wrong with an antioxidant, but it shouldn't make you feel any different. Maybe a tiny bit of caffiene.
Acai: Again, nothing wrong with an antioxidant, but it shouldn't make you feel any different. Not a horrible idea if you just don't eat fruit.
Diuretic: Great for bodybuilding competitions. Counter-intuitive to using creatine.
CLA: Does nothing (even in MASSIVE doses). Maybe I'm just immune. Interested in your results.
Bodystrong Fat Burner: Ingredients: 640mg of Eleuthero, Taurine, Caffeine, Green Tea Extract, Kola Nut Extract, Korean Ginseng, Guarana Extract... so it's just a big caffiene pill. Those are cheaper.
