Testosterone; darks v. fairs

Factual Questions
1

isn’t it true darker skinned people have higher test. levels than fair skinned people? especially certain races such as african americans? maybe not just test. levels but better body chemistry for BodyBuilding?

the really dark guys i see in the gym are generally slightly bigger compared to the average fair dude… even in the NFL, most of the white guys are smaller, granted there are some white guys who are just as big, but they are always not as cut.

any specific studies or documentation on a statistical correlation between:

  1. dark skin and test. levels/body chemistry conducive with hypertrophy.

  2. race and test. levels/body chemistry conducive with hypertrophy.

thanks.

i should have not mentioned NFL, they all use steroids. juicers and prohormone suppers should not be involved in this question.
