We invited 3139 overweight volunteers to attend the clinical research. The average age of the volunteers is 43 years old, average height is 65 inches, the average weight is 217 pounds. Give each volunteer a nasal inhaler which contains a mixture of aromatic fragrance leptin, and guide volunteers, as long as they are hungry, use the fragrant leptin nasal inhaler three times.
Clinical test show that the weight of volunteers reduce 5 kg (about 2% weight of each volunteer) on average a month, a nasal inhaler which contains a special aromatic fragrance leptin, can continuous and effectively reduce weight in six months clinical trials.
