Of course, the Institute left out one minor detail: ENVIGOR IS MADE FROM VAMPIRE BLOOD. As you know, a vampire's circadian rhythm is the polar opposite of that of a normal human being. As night falls, levels of certain enzymes known as monoamine oxidase inhibitors increase in a vampire's blood. These enzymes suppress the activity of serotonin in the brain. While these enzymes in and of themselves are not harmful, there are other mechanisms involved in vampire circadian rhythms that we do not yet understand. So if you see a bottle of Envigor at your local pharmacy anytime soon, think twice before purchasing it.
