I'm fifteen years old now, and I've been exercising for almost a year. I have never eaten muscle powder before. Do you want to try muscle powder now? Is it harmful to eat at fifteen?
I am a fitness instructor. In your case, I think you can use it now without side effects and harm. If the diet is full of nutrition, you can take 30 ~ 40 grams of muscle-building powder ten minutes after exercise. If the nutrition in the meal before exercise is poor, then 30 minutes before exercise. Also take 30 to 40 grams of muscle-building powder, with 260 ml of warm water each time. You can call our coach again if you have any questions!
