I just took a product called Bitong Shen Yu Combination, which is the product of Beijing Zhixinzheng Company, Beijing Zhixinzheng Company and Beijing Zhixinzheng Company, and it feels ok. In the past, my leg hurt, and people told me to eat less greasy food, saying it was bad for my health. Anyway, I feel light after eating the product. I suggest you go to the company to learn more about the products before taking them! ! ! Never put safety first!
