Superhuman Adrenaline is the biological ability of a DNA Alternate to voluntarily control their adrenal system, and enhance their adrenal responses, granting them heightened strength and speed. The hormone Epinephrine , also known as adrenaline, is one of the human bodies most basic, primal functions. It is secreted into the bloodstream when danger threatens or in an emergency. Often referred to as a fight-or-flight hormone, it plays a key role in an everyday human beings reaction to a high-stress, short term situation. It boosts the supply of oxygen and glucose to the brain and muscles, whilst suppressing other non-emergency bodily functions, such as the digestive and immune system. Present in all humans, adrenaline is used to equip a human being in the most desperate of situations, granting them the resources to escape, or to fight for their own survival.
When the situation calls for the hormone to be secreted into the Alternate's bloodstream, a much larger dose of it is released, increasing the physical performance by a considerable level. Like regular adrenaline, it provides a boost to the general physical attributes, but in this case to levels beyond regular human capability. With control, the adrenaline secretion could be moderated and released when necessary, but in its basic form, it turns up whenever they are most at risk.
