I wouldn't even know where to begin separating the two. I know people back home have worked with similar serums to the one used on me with less than ideal results. As far as how it all works I won't be much help unfortunately. The scientist who injected me was killed shortly after, I didn't get much time to question him about how it all worked. But whatever you need for samples just let me know and I'll come by and provide them.
Something like that. Even if some of them showed that's still better than none. They're teenagers, we all know they're going to do whatever they want, but I think we'd be pretty irresponsible if we didn't at least attempt to try to give them the information and resources to be as safe as possible.
