CWanamaker is right. Adrenaline is produced by the adrenal glands and released at the signal from the brain that the body is in peril. It's best used in the fight or flight response. Whether you choose to stand and fight or to flee, adrenaline enables the body to far surpass the physical capacities of the body at its resting point.
"super" strength is possible but only in the context that the strength is super by comparison to that of the resting state. However, this increased awareness caused by adrenaline is only temporary.
