How is endurance related to any of it? Eg I have very high natural T, go to gym and I have zero cardio endurance, I never do cardio. A possible reason are pills against pregnancy for women -> they then pee out the massive amount of estrogen due to pills -> that estrogen ends up in the water which ends up in the environment -> which ends up in our tap water.
