There is indeed a weight loss expert on WeChat-Zhang Yaru! I bought products for her years ago, and answered whatever I asked when I didn't pay. I stopped talking as soon as I paid the money, and I answered for a long time without telling you how to take this medicine and how to use it. I didn't say anything. She is an extremely irresponsible person, and all the products she sells are useless. Those are fake! Don't be cheated like me!
