What are the health risks of using HGH?

I work out daily but I have stopped seeing improvements in my m. As I was doing research today, I came across a product called GHR1000. I believe it is a herb that stimulates GH release. Will GHR1000 add m and if it does what health effects does it have. Finally, I am planning on participating in college athletics next year. Is GHR1000 a banned substance for athletes?
