Phendrexin doesn’t help you to lose weight, because it doesn’t have any of the right ingredients. They have to draw you in with a faulty auto ship program that doesn’t mention the fact that they don’t offer you a money back guarantee. And they have to hide their ingredients so that you won’t know how worthless their formula is among other things. With Phendrexin, you can guarantee that you don’t see results. But by their own description, you will probably suffer caffeine related side effects. Either way, it would not be a recommended product of any kind.
