Phen375 claims that you will finally be able to lose weight. They claim that it will burn fat, increase metabolism, and even suppress appetite. Phen375 claims that you will finally be able to lose 3-5 pounds per week without a real struggle and without any hassles at all. They claim that it is a prescription grade over the counter supplement that plays as an alternative to Phentermine. This being said, Phen375 doesn’t have any of the right ingredients, two of their ingredients really don’t promote weight loss at all and the other is the all too common caffeine. They don’t have any appetite suppressants, and they don’t have the right amount of caffeine to burn fat. Phen375 is by no means prescription grade, no over the counter products are. We would not recommend using Phen375. It will not promote any weight loss results or benefits.
