It does what it says it will do. I've felt that kick of energy after drinking the tea. It does not taste good, but my mother always told me if it tastes bad it's working. I've had the bissy tea (as Jamaicans would call it) before as a child growing up and I can stand by its effects. I did realize that if I drank it too fast the caffeine that is in this product does give me a jolts and jitters after, so I learned by lesson there to just slowly consume over at least a 10-minute period and not guzzle down the thing in 2. As for the cleanse part I still have a ways to go but I will continue using this product.
