I win at pretty much everything I do, I've always perceived myself to be a winner and more gifted than my opposition. I tend towards sports and activities that allow for this. As a kid computer games, nailed it, as a young adult skateboarding, nailed it, as an adult amateur kickboxing (13-0), then American football 4 seasons at RT ain't missed a snap and maybe 2 qb sacks allowed (basically with the qb rolling out past my pocket edge because of backside pressure).
Study on the winning effect:
"The men who believed they had won received an average testosterone increase of 4.92%, while those convinced they had lost dropped by an average of 7.24%. Overall, men who thought they were winners had testosterone levels 14.46% higher their deflated opponents."

That's likely better than any supplementation, without just straight replacing test.
