Now I will add muscle powder, and the dosage is half of the recommended dosage each time. I don't drink when I sleep. I just drink it after exercise, three times a week, and every time my blood sugar test is within the normal range. I think whether, when and how much muscle building powder can be added is based on the premise of not causing your blood sugar fluctuation, so you can judge according to your blood sugar situation for a period of time before and after fitness. I usually exercise after lunch, and my blood sugar is usually 5 ~ 6 after fitness. If you don't exercise, lunch will arrive at 8 ~ 9 in one hour and 6 ~ 7 in two hours, so I will supplement it after exercise. The dosage of muscle-building powder is half of normal, and then the blood sugar will rise to 7, but it will drop below 6 before dinner, so the blood sugar fluctuates like normal people.
