Ive only read the origonal post, not all the replies.
I hear what you are saying. However, someone with the level of mental health issues your boyfriend has (just going on what you have described) may need more that testosterone to "fix" him. Sometimes its all in our heads and if we change our way of thinking it can change that too. I was on antidepressants for YEARS looking for some magic drug to fix me. Never happened other than temporarily. Then I started to refuse to except that "Im just a depressed anxious person" and after a while of really working on it, I wasnt. I refused to allow those thoughts into my head and although I have some mild emotional issues, they are not to the level they once were.
I hope the testosterone helps him though. Good luck
