We are sorry to hear that you did not have good results with the Lipo-6 Hers. While everyone's biochemistry is different, some stimulating compounds can cause irritability for certain people. However, this is not a common side effect for most people. <br />Without knowing how long you were taking the Lipo-6 Hers it is difficult to determine why you didn't see results but to be clear we recommend using the product for 8 weeks at a time. If you purchased one 60 capsule bottle and followed the directions on the label you would have been taking it for 2 weeks. This is not an adequate amount of time to determine whether or not the product is effective for you. <br />Also, it is important to point out what the product is specifically designed to do. First, it will elevate your metabolism allowing you to burn more calories than you normally would. Next, for most people, you will consume less calories as a result of the appetite suppressing effects. If you were taking two capsules per serving as directed I am not sure why you didn't notice these effects as most people do. <br />It is also important to understand what it takes to burn fat and lose weight. Even though we pride ourselves on our fat burning products we always explain to our customers and potential customers that there is no miracle pill out there that will allow you to keep doing what you were doing in regards to diet and lifestyle and burn fat at the same time. In order to burn fat you need to burn more calories than you consume on a consistent basis. As mentioned earlier, the product helps with this by burning more calories and consuming less calories than you normally would. But if your current diet already has too many calories per day then the product will not be able to help you. It is designed to supplement a sensible diet and if possible an exercise plan. If you do not exercise you can still burn fat but this will require you to consume less calories to compensate. <br />I hope this helps you in understanding what may have gone wrong for you. <br />Thank you for taking the time to submit a review!
