I have drunk two boxes of American Leatin's fast fat-burning green coffee, and the effect is not bad. I lost 4 Jin a month. However, multiple sclerosis has some side effects. She always feels thirsty and wants to drink water. She has no appetite and doesn't want to eat. My friend is constipated after drinking it, and nothing else. Some people say that after drinking, they feel flustered and their heart beats faster than usual. Everyone's physique is different, and the effect is definitely different. The landlord had better buy a box and try it first. If there are bad side effects, stop drinking immediately.
