Note: Among 100 slimming products, Qumei is the most cost-effective one (I really don't advertise), and its possible side effect is probably constipation, which may not happen (depending on your physique). In addition, American diet pills (with good brands) have a remarkable slimming effect, but the probability of suffering from heart disease is also extremely high; Thai diet pills will cause hallucinations and do great harm to the body. It's best not to use them. In addition, the drugs in mainland China have little effect, and those that are useful have a very high rebound (cheap drugs).
