Brawn or Brain?


Anabolic steroids, technically known as anabolic androgenic steroids (AAS), are commonly used by weightlifters to "bulk up." Norwegian researchers studied the brains of 82 weightlifters who used AAS for more than a year and compared them with 68 weightlifters who had never used them or other doping substances. Users had less overall gray matter and evidence of accelerated brain aging.

PositiveTip: Avoid the use of AASs and prevent the neurotoxicity of these substances which can decrease cognitive function.
