One of my friends, a huge guy who competes in the strongest man competition, had bought some IGF-1 vials. The brand name was Nutral with lot number 050303. According to the label it contained 1000 mcg IGF-1 LR3 in acetic acid. He lifted his shirt and showed me his body. He had blue coloured bruises alike spots on his body the size of a hand, with fluid retention underneath. Later he confessed that they had lasted for weeks. I became very curious and tried to find a laboratory that had the capability to analyse complex proteins. I found one in Germany.
