i been on hgh for 11 weeks now, started at 25 iu per week, and now i am up to 50 iu per week, protocol 5 on/2 off. I have been eating a lot but clean, and have not gained any fat thanks to gh. However, my goal is to gain muscle mass, how long do you think i will start seein some increase in muscle mass. I know 6 months is usually where results emerge but anybody experience muscle increase before then. I am first used jinotropin, and now i am using prescribed norditropen.
