Pay attention to the authenticity of nutrition when choosing. There are many fake methods on the market now, and people who don't understand it are easy to be fooled, let alone online. Nowadays, there are many fakes, some of which are packaged by foreign brands, some of which are sold in China by companies established in the United States, and some of which are sold in China by their own brands. Anyway, they all have their own brilliant ideas, so I won't say anything ugly.
For example, in the United States, 5 pounds of protein powder usually costs more than 20 dollars, plus freight. Can the dealer's profit be sold so cheaply? Some coaches can't see it, but fakes will be exposed after eating for a long time, because it has no effect. As an expert, many things are not convenient to talk about online, but there are no problems with the brands sold in our store. You know, what you say online will be very troublesome. If one day the illegal dealer sees me, I will be disabled.
