About one month into taking the medically supervised growth hormone, HGH, I began to notice some racing thoughts, to the point that I felt a little bit jittery. At this point, I had gone from 4units to 8 units per day. I still felt pretty good and physically I can't say I noticed a difference but I did feel like my muscle recovery was a little bit better. It was about at this point, I had my first follow up appointment with my doctor and he assured me everything was ok and wanted me to continue to increase my dosage 2 units per week. I began to experience some swelling in my joint area to the point that my skin felt like it was burning. This subsided after about a week or two. One of the things I noticed that I liked very much is that my fast twitch muscles improved. My next post will describe some things that really had me concerned. Talk to you all soon. dm
