Let's talk about muscle powder first, which is called MASS in English, which translates to aggregation. Most of the ingredients (50%) of this powder are still protein, but there are many other supplements, such as sugar, fat, carbohydrates, creatine and so on. It can provide considerable heat and muscle supply. It is very suitable for fitness people who are thin, need to gain weight, have a fast metabolism and are not fat after eating. But it is still protein powder in essence, but the protein powder content is low and the price is relatively cheap. As for whey protein, vernacular is high-content protein powder, many of which are above 90%, some are 100%, and other additives are very low. This protein powder is more expensive, but it is very suitable for fitness people who need to gain muscle, reduce fat and control calories. Especially for people who lose weight, a lot of aerobic exercise will not only release calories, but also lead to the loss of protein. If you lose weight, you will lose muscle. It is the best way to supplement whey protein in this way.
