I must say, I used a 60$ 1mg IGF-1 LR3 vial and it seemed to be G2G. I did not gain any monster size in 4 weeks of use off course, but sides were g2g, the typical sides described for IGF-1 or insulin. So either the IGF-1 was real, or it was plain long acting insulin. My melanotan was also very cheap and G2G, I got a deep dark tan, and crazy sides.
