Very easy to use, once a day in the first week, and twice a day thereafter. I used it according to the above instructions. Is it convenient? They are all eaten after meals. The price is acceptable. /kloc-I bought two boxes at 0/00 yuan a box. Now I ate a box and lost 6 pounds. Generally speaking, it's not bad. By the way, I bought it at Lizi Shopping Center. It was introduced by my classmates.
