Search on LR3 IGF-1, normal IGF-1 would not be used at all, not it is not HGH but in part they are related. IGF is 83 amino acids not 191/192.
IGF can show a small amount of results in a short period of time, HGH takes much longer. I have never used either because really unless you have money to waste, these are drugs for the big boys. Cost versus gains are very poor.
