Phentermine is used as part of a short-term plan, along with a low calorie diet, for weight reduction. It is used in obese patients who have not been able to lose weight with diet and exercise alone. Phentermine belongs to the group of medicines known as appetite suppressants that will significantly decrease the desire for extra calories, speed up metabolism and increase fat burning. Recommended dose is 35.7mg per day for 3 months, followed by cycling off for an equal period of time. Often patients will switch to 5-Amino 1MQ or the Elite Weight Loss Stack I during this break. 5-Amino or EWLI may be used in conjunction with Phentermine
