1.More stable

HGH being purely 191 amino acid hGH, is the only hGH in China that can be stored at room temperature for a long time and are stable at 37°C for about 2 months.

2.Raising much less antibodies

191 amino acid hGH proteins are identical to the natural hGH, therefore pure 191 hGH causing very little antibody formation in the body. However the 192 amino acid hGH is different from the natural hGH, thus causing stronger antibodies formations in a majority of people. These antibodies will make the hGH stop functioning. This is why the US FDA is currently banning 192 amino acid hGH products now.
