Adrenophine was a commonly used stimulant that was used as a common reviving agent. It's heaviest use was by military field medics, due to its ability to jolt a patient to life or keep a wounded soldier stabilized for short periods of time. It had a dark blue color, and directly affected the adrenal and central nervous systems.
Adrenophine was typically injected using a dermispray into the neck. Within moments, the potent drug would jolt the body back into consciousness, and could even stimulate neural activity in the brain.
