Professor Yan? I have never heard of 1, but I have used many methods to lose weight for so long! So let me explain that trying to lose weight through weight-loss products must have side effects, but we must distinguish what side effects are, and side effects are not toxic side effects! In fact, the side effects have little effect on the body. I have taken at least 8 slimming pills myself, and I took them before marriage. I am in good health now, and the baby is born! Postpartum fat explosion is also 52 pounds thinner through diet pills! There is nothing wrong with it!
