Hey brother, I prefer to do the standard blood work test. Based on gh serum and igf-1 you can get a pretty good idea on how legitimate and dosed your gh is. I do 10iu fasted, 3 hours after that get your blood drawn. Your gh serum should be elevated. As for igf-1 its best tested after 1-2 months on hgh, I prefer 2. Establish your base line igf1 then when you test 2 months in your igf should be elevated roughly 100 per iu of legitimate gh. Again this will be subjective person to person but gives you a rough idea. As long as its elevated though thats all that matters. For myself 5iu a day of pharma gh put me around 500-600 igf1. And your 10iu gh serum should be 20+
Hope this helps
