Thetaline is a hormone and a neurotransmitter found in Alphas. It has properties similar to adrenaline in humans and other Beta species. It increases heart rate, constricts blood vessels, dilates air passages and participates in the fight-or-flight response of the sympathetic nervous system.
The major physiologic triggers of adrenaline release center upon stresses, such as physical threat, excitement, noise, bright lights, and high ambient temperature. All of these stimuli are processed in the central nervous system.
Thetaline has a number of other effects that separate it from adrenaline, and make it the key to Alpha species’ physical superiority. When into the bloodstream through the stress of combat, thetaline provides a significant boost to an Alpha’s already significant strength and speed.
It also works as a pain killer and natural antibiotic. But most impressive is the effect it has on damaged cells. It accelerates cellular growth by nearly thirty times. Open wounds and broken bones heal within minutes to hours.
The pharmaceutical divisions of all twelve mega corporations are needless to say very interested in adapting a synthetic version of thetaline for use on Beta species. But the miracle hormone has proven to be lethal to other races. Causing immediate heart attack, or cancer from the accelerated cell growth.
Such research has been officially banned. But rumored to be still under development in secret labs around the galaxy.
