Tony 'Hulk' Geraldo , 49, and Alvaro 'Conan' Pereira, 50, regularly inject steroids used as a vitamin for cows and horses - which their doctor has warned them not to take. They also consume up to 12,000 calories between each day - and often scoff 12 bananas and six egg whites before a work out. Their biceps are between 63 and 71 cm now.
