I am interested in trying an IGF-1 kit(s) and am wondering two things. What kind of resuls has anyone experienced compared to roids and has anyone been able to get the kind that is introduced as a virus into the bloodstream where as you will be able to pruduce these levels naturally without further use of additional kits. In reading about this issue I think in the future that this may be the best and least hazerdous on the body for males and females to make terrific gains for size and lean muscle. Any thoughts.
