My friend, you seem to want to gain weight. You are so happy. Everyone else is worried about losing weight, but you don't have to lose weight, you have to be slim. So you don't have to take diet pills. Maybe you are still young, and you will naturally get fat at a certain age. Even if you want to get fat now, don't take medicine, it will be unsafe. You must believe that all drugs are toxic and harmful to your health. As long as you stick to a normal diet, you will be healthy, whether you are fat or thin.
