Hello! From your account, I can answer you in two ways. One, first of all, goji berry powder is not fake, is the real thing, eat some taste bitter, is to goji berry stalks, leaves, roots as raw materials processed into goji berry powder, this kind of powder has a slightly bitter taste, you can not say is fake, it is also goji berry powder; Second, is to use goji berry drying after powdering, is also a goji berry powder, this kind of powder to eat there is no bitterness, so goji berry powder, depending on the raw material is what is it. I said the above two aspects are with goji berries, if not made with goji berries is not goji berry products, is fake. Understand well, goodbye!
