To lose weight. Water weight primarily. Most boxers do this, its no real secret. Mayorga just got caught. They help you to piss out a lot of fluid in order to make weight, then you can gain it all back after the weigh in. That's why Mayorga told Oscar, "I weigh 170 lbs, its on..." or something to that effect. He wanted to come in the bigger man, thought it would give him an edge, just caused him to be slower and get winded easier unfortunately. Don't over react folks, many many great fighters take injections to lose weight like this.
