Why is it so cheap? If we don't compare this WPC80 separately, 1KG is almost 70 yuan. Not very cheap, just because the brand protein powder is too expensive. Five pounds costs 788, which is more than the average person's consumption. Why is the brand so expensive? Because its price includes its brand value. The advertising value, various expenses of store sales and adding some trace amino acids and essence to his protein powder are slightly complicated, so the price also includes technical value. Of course, the ex-factory price can only be lower than the sales price by 60% or less.
This contrast makes WPC80 feel cheap. In fact, whey protein powder was a by-product of dairy products for a long time abroad, and many of them were thrown away as garbage until the fitness industry discovered the efficacy of whey protein powder. The price will go up! But his own value is not very high. The price of WPC80 is reasonable.
As for whether you can eat, there is no doubt!
