I have never done roids but to say that higher levels of the male hormone testosterone would not result in a more ferocious person is just nonsense. On average the male body does like 7-9mg a day of testosterone, thats 49 to 63mg a week. A logical person could not sit there and say that taking 8x the normal dose your body puts out would not change the psycological side of someone either consciously or subconciously. Either way the rage part could be a myth because rage is defined as a uncontrollable outbreak, but how could one not be more aggressive?
