I often eat it. Cover this thing after eating. Ensure tightness. Powder, sugar. I'm afraid of bugs and humidity. Ensure dry, according to normal habits, a can of 2270g will not go bad for 3 months. And then there is. This kind of food. You can eat it when you are not exercising. Because normal people who don't exercise need 50g protein every day, the exercise intensity is high, which needs to be supplemented by protein in food. You don't have to worry. You can ask me again if you have any questions.
