This is just my personal opinion, so take it for whats its worth. I also mean no disrespect, so I hope it doesn't come off that way. Reading your questions regarding hgh dosages and the use of insulin leads me to believe you are new, or at least, relatively knew to using hgh. Before adding multiple compounds to compliment another, I would first run the hgh and do further research on the use of insulin. It is not something you want to go into blindly. As I said, its just my opinion, and everyone knows what they say about opinions.
