Works for me.
I'm no scientist or fitness expert but I feel an improvement even if it just turns out to be the placebo effect isn't that what we're all looking for out of this product anyway to feel improvement. I can say that while I don't feel any kind of jittery energy like too much caffeine or an energy drink if I take this too late at night it's difficult to go to sleep so that tells me there is some sort of metabolism boosting property.
