If you can't buy it at the drugstore, I suggest you go to the gym or Taobao. Domestic brands are only Kangbite imported brands, and many of them have been exposed to fitness champions before (I have also drunk champions before). In fact, the content of most protein powders is basically the same, as long as you don't buy fakes. If you are from Qingdao, I can recommend an agent who specializes in selling imported protein powder, both domestic and Kangbite.
