The weight of 8 Jin of muscle-building powder is 3600 grams. There is a small spoon in the bottle of protein powder or muscle powder. Generally, a spoonful is about 30 g, and eating 2 spoonfuls a day is almost enough, that is, 60G a day, so 8 kg can be eaten for about 60 days. If you eat 3 spoonfuls a day, you can eat it for 40 days. If you don't do much exercise, a day 1 spoon is almost enough, of course, this is under your proper diet every day. If you do a lot of exercise, eat 2 to 3 spoonfuls. If you get up twice a day, once in the morning and once within half an hour after fitness (because half an hour after fitness is the best time to supplement protein, and then the effect will get worse and worse as time goes by, and the effect will be very poor after two hours); If you get up three times a day, you can get up once in the morning, once before exercise and once after exercise. Another important point is that these supplements should use warm water instead of boiled water.
