at first I did the typical 2-4 iu a day shooting it at night or in the AM and it really did nothing, I did that for over 7 months then a year later I started 4 and 4 after someone telling me to give it another run and let me tell you I turned into a fat burning machine and I started seeing nice muscle gain nothing crazy but def gains I can only credit the GH for in addition it took care of slight acne i got randomly on my shoulders.
Now I have no doubt it made me tired, some days from one second to the other id get tired to a point where I can fall asleep standing up.
