I'll let YJ explain what an uncoupler is. I'm sure he has a bunch of articles ready to go =)
As far as people's results with it. They have been excellent. I ran a 2 week cycle of it. My results weren't earth shattering but I know I didn't keep my carb level up enough. There is no point in taking it if you don't keep your carbs high. I believe the recommended % of carbs is 30% or more. Someone correct me if I'm wrong.
