When you fill up your Testosterone Bar (Blue Bar in upper right hand corner of the screen) and the whole Bar, including the Circular piece to it's left, glows blue, you can activate your Full Testosterone Attack with either (Tab or Right Thumb-stick). This bar is filled every time you cause damage to an enemy.
