I have recently started doing HGH injections. I started about one week ago. I am doing 5 days on and 2 days off. 4 I.U. per day and splitting them to morning and night. I would like to know what to expect and when the signs that it is working will happen. I am feeling nothing and I need some info from a person that has done this before. The bottles are not labeled and I know that is a red flag. however I received them from a good friend of mine and he would never burn me. That is my confidence in all this. So if someone could tell me how long it should take. I would love info. Thanks M.M.
