I had IGF-1 blood test done before using HGH-DUDE.com's HGH. I Had another IGF-1 test done after using their product. The test showed there was no change in IGF-1, which means there was ZERO HGH IN HIS PRODUCT. I had received HGH from another supplier, took same amount of hgh and there was an IGF-1 increase of 65. Also T. cypionate was missing authentification on box. He even ripped me off on the EMS $40 expedited shipping charge and sent it China post instead which took 20 days, as well as $650. Leo from hgh-dude.com is a thief, rip-off, scam artist, scum of the earth.
