Hello to everyone out there. I have been using pharma grade growth hormone for 5 months between 1 and 2 milligrams per day. Last year I used a generic source of growth hormone and I did not notice any difference. If money is no object then go with the name brand, otherwise generic growth is the way to go. There were no bad side effects and always notice I have a better sleeping pattern. Research and pick carefully. I pray it is not placebo.
