First, packaging. If you have used Nutrilite products before, you can compare the packaging. Generally speaking, as long as Amway has not changed the packaging, the same products will not be much different. I also want to remind you that the products sold by Amway stores at the original price are all bar codes with product identification. The biggest function of this bar code is to uniquely identify this product, and at the same time, it can track the sales and purchase information of the product. In other words, through the sales management system of Amway, we can find out whose Amway card they bought. Because of this, many people who sell domestic Amway products at a discount online will deal with the bar code on the products, otherwise Amway's business supervision department will easily find out who is responsible for the illegal delivery. From this, we can also know that the products purchased at the original price must have bar codes, but most discounted domestic Amway products will not have bar codes, unless the direct sellers who hoard too much goods have no plans to engage in Amway direct sales for a long time and are eager to clear the warehouse and cash out, but these products are generally in the majority. After recognizing the package, I changed the products inside. Previously, there were many versions of Nutrilite product identification instructions on the Internet, saying that they could be identified by color and taste. In fact, this is very unscientific, because we know that Amway Nutrilite products do not contain any preservatives and pigments. It is precisely because preservatives and pigments are not added that the color of the product will vary from batch to batch. Nutrilite products have dozens of varieties, and the difference between raw material planting and production environment will be reflected in the color difference of Nutrilite finished products. Therefore, it is unscientific to distinguish whether a product is genuine or not according to color. The key is to choose a guaranteed merchant to buy. Judging by personal experience and experience.
