I did at one point try taking pregnenolone to increase my testosterone. My testosterone levels were never actually low, but they were on the low end of normal. Pregnenolone is known to increase testosterone levels when taken by a normal adult male, and I was thinking that having higher testosterone might increase my confidence and decrease my depression. That lasted about a week, and I can't say anything positive about the results.

It made me feel worse in nearly every area I was trying to improve by taking it. That experience was also a big contributing factor in my decision to start taking anti-androgens even before I really came to terms with the gender identity issues I was having. Once I realized how badly testosterone was making me feel, I just needed to get off of it before it drove me to do something desperate. Of course, I am not you. Lots of people like the way testosterone makes then feel, and I don't think you're going to be able to know for sure how higher testosterone will make you feel until you try it. What I can tell you is, it did not take me long to figure out increased testosterone wasn't going to work for me. I don't think you have anything to worry about regarding irreversible changes happening if you only tried it for a week or so. The real problem may be finding a way to get it prescribed for you on such a short term trial basis.
