You sit in a chair, the guy puts on a pair of some sort of lead lined gloves and an apron, (god knows he cant get any on him) he reaches down into a cauldrin of sorts, draws the stuff into a syringe, then they inject it in you. Yeah, nothing could be bad about that,
but I had it done and I'm still normal, well, lets ask my wife.
No side effects that I know of, couldn't tell any difference in that and any of the other things they stick in us.
You'll do fine!
