By the time Coffeen left the Army, he’d become an exercise fanatic—he’d gotten into CrossFit and powerlifting, and eventually, bodybuilding. He knew PEDs were part of the sport, and he decided to try them. He eventually found a supplier overseas, sent a money order, and received vials of steroids in the mail. The vials didn’t come with syringes or needles—what PEDs users call pins—so Coffeen found himself in what he describes as a “veterinarian store,” telling them he wanted needles to administer a rabies shot to his dog.
