I will tell you what I did to see if mine was real. Take into consideration that I have been on GH for 8 months. I was using 6IU's of Humatrope. So, I took 10Iu's of the the Jin foer a few days. The numbness in my hands came back and lasted for a while. This had not happened in about 5 months. I am not advising you to do this, I am telling you what I did.
