This happened to me and i wonder the same thing. I am a young man with the same issue. The only issue is i got my testisterone tested and it was 699 (maybe thats low for me?). I dont habe libido issues (maybe at first) however i did lose about 15 lbs of muscle weight within 2 mths of tbi. Sometimes i wonder this and if my testosterone was normally just high.
I tried clomid and had some shitty side effects: floaters, brain fog, etc. It felt good the first couple days then went down hill. I did this supplement called red beast and felt good on that, however only recommended for short term use. I am considering long term products however want to maintain fertility (only have one kid thus far).
