First of all, there must be a reasonable basis for losing weight. Then, if you choose a slimming product, it depends on whether the product has formal procedures and certification by an authoritative organization. These should be carefully distinguished! You can ask him for the product certificate and certification, and see if you can prove that his product is an effective weight loss product certified by the state.

By the way, health food and food-grade weight-loss products on the market have no weight-loss effect. You can check whether the products are of these two grades first. If not, you can ask to see other qualifications that can prove the weight loss effect, and then check online yourself.

Just now, I went to check that the products that Wenwen helped you lose weight are OTC products and have been certified by the US Food and Drug Administration, so the products that Wenwen helped you lose weight are real. I hope I can help you adopt them!
