Brothers Tony ‘Hulk’ Geraldo and Alvaro ‘Conan’ Pereira, have both injected dangerous chemicals to make them look HUGE. As well as using extreme lengths to bulk up to a combined weight of 241kg, the brothers from Rio, Brazil, attend the same gym everyday and work out together for hours to improve their definition. Tony, 49, and Alvaro, 50, claim there was a time when they were ‘addicted to getting big’ but now believe they have it under control. Alvaro had been injecting his biceps and legs with a supplement – called Potenay B12 – on and off since he was 15 years old. Tony followed in his older brother’s footsteps. Taking their doctors advice, the brothers claim to have recently stopped injecting for health reasons and because their skin cannot stretch anymore.
