Haha, I used it. There is nothing wrong with my sex life, but when I get old, I feel powerless. I bought three boxes, and now I use one. Every time ML excites my wife. But I feel a little constipated after eating it. I don't know what's going on. I didn't do it every three days according to the instructions. I only use 1 tablet occasionally, once every 1 week. 1 tablet fits 40 yuan, which is very expensive.
