I don't know. I haven't used it. I was quite fat for a while. My friend introduced me to Viome slimming capsule, which is made of traditional Chinese medicine. As a result, I really lost weight when I took a shower for 6 days. Although I only lost two pounds, I have always been fat and never lost weight. So I continued to use it with confidence and gradually lost weight. Now it's really satisfying to see that I've lost weight.
