I have been running Serostim Phamacy hgh for serveral years. I have taken Small breaks but I have noticed my igf1 values are garbage now. I used to run 2iu and have 350-400. I have experimented with doses all the way to 10iu/day. I was just running 2iu for a couple months did blood work. IGF-1 220. I have gone off it again. Any ideas why this is? longer break ? I am not using anything that decreases igf. I am on test / primo at the moment.
