yeah bro, i love the igf, i get sooo lean and vascular, last time i did it i injected my bis, chest and calves, they all grew. My calves grew an entire inch, my arms grew a 1/2 inch and my chest grew a lil over a 1/2 inch. This and toremifine are musts for my post cycle therapy. It also helps greatly with healing. I had hurt my left pec right before i started the igf and it healed very quickly.
