An incredible Hulk-inspired bodybuilder is risking his life to pump up his muscles by injecting oil into his arms. Beefcake Valdir Segato’s huge biceps measure a staggering 23 inches as a result of painful synthol injections.The 48-year-old’s arms have doubled in size from 12in after he began injecting the potentially lethal oil substance five years ago - and now he wants to get even bigger. Valdir, from Sao Paulo, Brazil, is inspired by the physiques of Arnold Schwarzenegger and the Hulk and is proud to be known locally as ‘He-Man’ and 'the monster’ in the street.
