Performance-enhancing drugs run through every level of competitive sport, from Olympic podiums to professional locker rooms to high school weight rooms, and this National Geographic film looks at why athletes keep taking the risk. It lays out the actual pharmacology: how anabolic steroids build muscle and speed recovery, what they do to the cardiovascular system and hormone balance, and the physical toll that can follow years of use. Interviews with scientists and athletes fill in the human side, the calculation that trades long-term health for short-term strength and speed, and the pressure that pushes people at every level, not just elite competitors, toward the same choice. The film treats the science and the sports-world consequences as one connected story rather than two separate lectures, tracking how a substance built in a lab ends up shaping who wins and who gets caught.
