This is my first time trying hgh, Im 47 years old and I been working out for a while and was ready to start taking hgh. I recently purchased some hgh green top no labels plain white box...the source said it is jintropin, I have no clue if its legit. I had been on 8 weeks of riptropin that was legit. The one I have now when I pin myself there is a burn sensation but then goes away where the previous I had (riptropin) didnt burn at all. SO my concern is if this one I have now is the real deal. PLease help because Im new to the game and want to continue the hgh. Thanks so much.
