A Brazilian bodybuilder has grown 29-inch biceps, claiming that is the biggest in his country.The 43-year-old achieved his supersize look after injecting a mixture of mineral oil and alcohol to his arms. However, the mixture can cause horrific infections. People who have injected the material have had their arms amputated or have even died. But the Brazilian man isn't the only person resorting to using synthetic materials to bulk up his body, as many others in the bodybuilding community are said to be doing the same.
