Turns out the list of options I just received was just several Labcorp locations. So looks like I am going to Labcorp. Today or tomorrow. I kind of want to do it today just to get it out of the way!

I think I am leaning toward peeing in the toilet, get a little of my stream in the cup, quick fix, maybe top it off with some more of mine, swirl it around a bit, make sure the temp is ok. I just want to make sure there is a little bit of a human aspect in it. I am going to follow the dilute method so I don't think it will be dirty. I wish I could get some more insight, but from what I have gathered it shouldn't hurt me too much unless its super dirty.
