"i have taken tenuate for 2 months now and lost almost 20 pounds. this is huge for me as i had tried and failed to lose weight -any weight- on my own for years. in addition to helping me lose weight, on it i have more energy and a better mood, so i did some research and found that the medicine apparently also works on increasing the serotonin in the brain. good stuff - i&#039;ve been very happy with it."
