Let me tell you something. I didn't feel anything and didn't think too much on the first day when I first started taking it. But after a few days, I felt warm in my stomach and gradually took effect. After all, it is all natural. After one month, I weighed myself and lost weight 12 kg. The swimming ring on the belly has become smaller, and the whole person has relaxed a lot. But I tell you, I bought it at "Korea Music Shopping Network" and it has a good reputation. You can try.
