It is very good, IMO. I have used Humatrope, Serno, Somas, and the Jin. Humatrope and the Jins are the two best. You cannot go wrong with them. Hum and Jin, I cannot tell a difference.
Been using 5-6IU's a day of the Jin for about 3 months. The more food I eat the leaner I get. One side from the GH I get is vascularity. It's a good side.
I have been cycling for the last 10 months with GH. Now I didn't get a blood test before the cycle, but I got one a few days ago and my blood is all in the normal ranges. Liver was just out of normal. Lipase was a little high. So, i am thinking that the GH might be helping... It's just a thought. I also take a lot of nutrional/natural supplements.
