It shouldn't be useful. I have bought Happy Buy many times, and the conclusion is that it is best not to buy something without a brand, and I will regret it after buying it. No brand refers to some brands that have never been heard of and have a short time to market. I found that brands have been reliable for many years, and of course it depends on factors such as word of mouth, effect and service. Because the product that is not easy to use is untenable, it may be sold for a few years. I used to follow the trend and buy a few brands and new products that can only be seen when I buy them happily. I feel very sorry. Later, I basically only bought brand things, and I felt good. Don't get too much hope for things like diet food and diet pills. I used to buy everything when I saw advertisements, and 99% of them were useless. If it is useful, it will definitely bounce back or even get fat within two months after stopping the drug (in fact, most of them will bounce back after stopping the drug for a week or two, and two months is a long time). To really lose weight, we must rely on the laws of diet regulation, exercise, drinking tea, ensuring work and rest time, and get rid of hobbies such as smoking and drinking. Don't go on an excessive diet, or you will gain more weight. I have experienced it personally, really. Keep a normal heart. It is best to extend the weight loss cycle to more than half a year. Don't expect to lose a lot of weight in a month or two, lose weight faster and rebound faster. It is the healthiest to lose about a catty a week on average. Back to Happy Buy, I often look at its website. Weight loss products have the most bad reviews. Now many comments have been blocked by them, which is not objective enough, but it can still reflect some problems. I feel that those people believe in the boasting of happiness too much and their psychological expectations are too high. If you subtract 50% of their efficacy and extend it twice as long, you may not be so disappointed. There is also the product called bitter gourd liposome, which was sold in Taobao at least five or six years ago, and it was very cheap at that time. Now Happy Shopping is much more expensive. As for whether the effect will be better, only those who have tried know. Finally, there is only one suggestion. If you have any bad symptoms such as diarrhea and dizziness after eating it, don't eat it again, but stop it immediately, because many weight loss products add western medicine ingredients in pursuit of quick results, which is not good for your health, and the side effects may be long-term, which will hurt your kidneys and even affect your fertility. So, if you have bad symptoms, don't feel bad because you spent hundreds of dollars. Throw them away at once. The problem of hurting the body is not solved by money. Finally, I wish you health and happiness and success in losing weight. Health is the premise!
