Pete in baseball the top performers A-rod Gary bonds use steroids, why ? its gives them strength and additional endurance.
Wrestlers, why ? strength and endurance.
Body Builders, Strength Training, Cross fit, adds strength and endurance, Body Builders get much bigger and weight lifters stronger.
Fighters the same strength and endurance, fighters have always used peds thats why they test them before each fight. Actually fighters are tested more than most all other sports.
Pete common sense if there was no boost by taking drugs strictly for Performance enhancing no one would do it.
Just the name Performance Enhancing Drugs tells you what they do and their purpose
I disagree with you on this one
