Hello. I used the therapy from hrtguru.com/average-monthly-cost-of-hgh-therapy. It is injections. I took a course. The effect is very good, I injected myself Omnitrop, $600, very satisfied. My muscle mass has increased, my appearance has become better, I can say that I have become 10 years younger. So don't be afraid of this therapy. If you watch your appearance, then this procedure is for you.
