I've been always asked by customers on insulin, and how to incorporate it. I would like to mention and emphasize - Using insulin is not only somewhat dangerous practice it also sabotage insulin sensitivity. IGF1 is not only an extremely powerful anabolic agent, it has a distinct synergistic effect with GH, and it increases insulin sensitivity and optimizes the metabolism.

Here is a relevant older thread on this - GH, IGF1 and should I combine them ?
