It is quite common to have some sort of plot device to justify how the TF trigger got to the Average Everyman or Hot Co-Ed who will be its primary subject. I myself have used random magical computers, random improper scientific waste disposal, and random tall Jewish professors. However, when you make a point of telling us how much of a loser your protagonist is, how deviod of ambition he is, how he's found an Internet girlfriend without mentioning any effort on his part whatsoever, and then the vials, with instructions, are literally delivered to his front door by someone who knocks on the door and runs away, which he then drinks despite his specifically mentioned better judgement even though he knows it could be poison, then I can't help but feeling you are, somehow, inserting your desires into the story to a level that is above average even by furry standards.

I'm just sayin'.
