Steroids is not the same of testosterone.

[@reeyees50]

Doubt, then why many men on sports take anabolic and androgenic steroids (testosterone derivatives) to become more aggresive? Basically the opposite of castration

[@Nic-xr8sd]

Steroids and testosterone is not the same thing. Plus most of athletic people takes a lot of steroids thats the reason why they become so aggressive..
