I have a hard time believing this. My testosterone level is 1,114 ng/dL naturally and I sure don't feel pumped full of energy and ready to go all the time (I'm 24). And I was even a D1 athlete. All it means for me is a greater risk of prostate cancer (which both my grandfathers had). My doctor was concerned about it being that high.

Also, I think the rumors about men with high testosterone being aggressive or having a "player/alpha" mentality have been disproven; I don't remember which journal that study was in. I'm about the least aggressive person I know. If anything, I'm too passive and have a difficult time expressing what I want.
