I got 100 ius of HGH from a friend. The vials have blue tops on them and are really loose. The labels say for lab research only and 10ius with a batch number. It looks so shady. I put 2.5 ius on an EPT pregnency test and it didnt read anything. Not posiitive or negative. What does this mean? I know this is not a perfect science but a start anyway. Something tells me to get my money back. Input please.
