How Does Power IGF Work? Power IGF Ingredients Well, I'm not sure about all the ingredients that are used in it but they are natural. If your body isn't performing efficiently it wont matter how much or how often you lift and how many protein shakes. Do you diet and exercise diligently but still are not achieving the results you desire? Looking for a way to enhance your performance and gain lean muscle faster? I'd like to be honest with you on this point, but did you see where I was going with that theory?. Power IGF can give you a distinct advantage.
