Okay here it is. I was taking up to 10 iu's of HGH. Began having unplesant side effects, tapered down to 2ius etc.. even then took about 3 days off due to traveling with job. Now I have been back on meaning increase amounts up to 8iu's. However I am not having side effects no joint problems or swelling. I have started a new box, however it is of the same product. Do you think my body has adjusted or could my growth be bad ? I figured to take my higher level's and if I got side effects then I know it is good, or at least I kniow it is working as crazy as that sounds,
