Unintended Side Effects

Science has always been humanity's friend. It is what inspired scientists and doctors to create vaccinations and cures for diseases. But what happens when it goes too far?
Eight unfortunate teenagers are kidnapped from Paris and taken to northern France to partake in a new experiment; health enhancers to boost human characteristics or give humans characteristics they might not have. Some side effects include nausea, moodiness, and exhaustion. They tried on older candidates, but it had some, consequences.
The experiment was supposed to last for a month in order for the enhancers to take effect. However, what happens when the enhancers take effect in only three days? Nothing good, that's for sure.
