I am 37 and went on androgel because my testosterone was 201, and I had symptoms of depression, anemia, and being very tired. I have never had any sexual issues although now I am even hornier. I went on 2.5G a day to start, and my testosterone went down to 171. I like most of you felt better at first. I am on 5G and after several months on that I am doing well and my testosterone has doubled. Why? The body recognizes the hormone, the pituitary gland makes LESS L.H. (lutinizing hormone) Please excuse the spelling. This is the hormone that tells the testes to make testosterone. If your pituitary gland and testes are working at all, they will slow down production even more. It takes months on one dose just to check bloodwork and then months again on a new dose to check again. Hang in there guys. Hope this helps
