Yes, I'm aware of caffeines functions as a catalyst of energy. I'm merely pointing out that chief difference I was attempting to point out, is that caffeine's spearhead effect is in fact the blocking of Adenosine receptors in the brain. The energy consumed afterwards is mostly caused through the body assuming it has more energy to burn than it actually does.
I also think I'm mixing up my adenosines. I'm fairly sure the one chiefly used in sleep encouragement doesn't have the phosphate branch.
A quick google confirms my error.
My bad.

Also, good to see you Ciro. It's been some time.
