Do Quadra cuts extreme work?

I was wondering if this actually works because ive been using it for like a week, and I haven't been feeling any different. I don't even feel jittery or anything. My body temp seems normal despite the thermogenesis, I am rather fit, though I need to lose about 5 or less pounds of fat. Despite this seeming ineffectiveness, I can testify to a great decrease in appetite. If these don't work, what does? I have a rudimentary six pack but I really want to get more cut can anyone help me?
