Yeah you'll get the peanut butter shot. Don't remember what it is thats in it. It hurts a little when you get it and its sore for a couple days but it's not that bad. People just seem to hype it up. You all just bend over around a gurney and about 6 of you get it at a time and then its all over. Its really not that bad, don't you worry. This is boot camp we're talking about, don't sweat the small stuff, trust me.
