Fat Burners, ingredients vs. caffeine, and Hot Rox results

I used to work at GNC.  Most fat burners are based on the idea that if it can get your heart pumping faster that it will cause your body to need to burn more fat through workouts and everyday activities.  Which is why the majority of them are just caffeine pills.

However I read this article online regarding how the body burns fat and an alternative to the ECA stack.  Basically it talked about the hormones that attack your fat cells during lipolysis.  My first thought was I should just get more of these hormones in my body.  However thats steroids.  So then I did some research on if there was any supplements or herbs that could activate or increase these hormones.  Basically the article said that yohimbine and L- Arganine have shown the ability to affect these hormones.

Hot Rox contains both of these imgredients which makes it seem different from others I have researched or takem.  Has anyone tried Hot Rox or a yohimbine, L Arganine stack?

Wait, not yohimbine and L Arganine, yohimbine and L Tyrosine.
