I have used countless health care products and drugs to lose weight, even the legendary one is either thin or dead. It's useless for someone to give you a definite answer! ! ! Never think about these things. Most of those drugs are effective with laxatives and diuretics. You seem to have lost weight by expelling water from your body and stool. This is called losing weight. And it is a three-point poison. Please consider your health. As for why all diet pills in Thailand are effective, I can also tell you responsibly that two very important data in the diet formula are heart rate and time. In other words, the heart rate exceeds 60% of the maximum heart rate of the human body, which is called aerobic. That medicine is to make your heart beat for an hour, and you will feel it one day and one week, hehe. Believe me, it took me two months.
