Doping in sports has been going on forever.
Even when I was high school, in the late 1950s, football players would get scholarships to prestigious academic universities.
They'd come home on xmas vacation, a few inches taller and wider, and 50 lbs of muscle heavier.
How? They didn't know but they got steak three times a day in the jocks' dorm, and yellow pills with each meal.
Except on weekends. Then they got blue pills.
