Hello! Green Island is happy to answer your questions! I have been eating milk powder for more than 20 years, originally to gain weight. I have every right to say so. The price is not expensive, but there is good milk powder. I suggest you eat Nestle's milk powder. If you want to gain weight, eat it with nuts and have a cup of warm milk and protein powder in the morning and evening. Keep drinking. Nuts are preferably walnuts. If you don't like walnuts, red peanuts or almonds will do. If you like dessert, you can eat more chocolate, and it is best to eat dessert immediately after meals. This fattening effect is the most obvious. Then there is a midnight snack. If you have a good appetite, eat a midnight snack every day. The effect of fattening is particularly obvious. I hope the answer from Green Island can help you. If you are satisfied, please help the island adopt it. I wish you and your family happiness and health forever!
