Ok hgh can be tested blood only. Also if you are 30+ your hormone level naturally. Goes down. Although your strongest yeArs are 30-35 as a human yor dr can give you a test and if you show a decrease in these levels he can legally give u a topical cream that is essentially hgh. It's not that hard. I have not read through the thread nor am I accusing Gsp of anything. I'm just giving some insight to what I know.
