I have never seen MGF work for anyone I know. I have used it once, and saw no change. IGF LR3, on the other hand, can be a great tool for adding size and creating hyperplasia. I have had good experineces using it on it's own and better experiences using it in conjunction with GH. The more I read, the more I understand that there is a chance that IGF can cause issues though. The best way i can describe it, as told to me by a top HRT Dr. In our body, cells mutate and die. This is constantly happening in a healthy body. When they don't die, and these mutated cells continue to grow, you have cancer. With GH, cell growth still has a set of "checks and balances" that limits it from causing mutated cells from continuing to grow in a healthy body. Pure IGF does not have these same "checks and balances". Ran alone, IGF MAY allow mutated cells to survive and continue growing when they may have otherwise died off. I was recently told to always combine IGF with GH to impose limits on IGF. Now this science is way beyond me, but I have heard similar ideas shared by other Dr's. 

I would combine a couple iu of GH along with your IGF, and yes, I believe that this can help speed healing of injuries.
