Testosterone

I've been depressed since last June. Been on a cocktail of lamictal, latuda and effexor since October (they were added one at a time by a couple different doctors) . None of them seemed to do anything, so I decided to be my own doctor and ordered a supplement that claims to boost testosterone by almost 200%. And since I started taking it I feel MUCH better. So I decided to experiment again and stopped taking it for a week... Back to feeling like shit again. Started back on it after that, and guess what, felt way better again. But while I was depressed, blood tests said my testosterone was "normal"... So I'm wondering if anyone else has any stories that relate to testosterone levels. I've read all the articles on the web but they all come from doctors or writers who can't relate. Note: of course this only applies to males
