Romario risked his life injecting a cocktail of oil, painkillers and alcohol into his biceps, called synthol.
At one point, doctors thought they would have to amputate both his arms, which had swollen to 25 inches after the muscles started to solidify.
The 25-year-old from Brazil, says: I remember the doctor told me that they would need to amputate both arms they said everything in there, all my muscles, were rock.
Romarios dangerous obsession started three years ago after he moved from his hometown to Goiania in Brazil.
He recalls: I saw some really big guys in the gym with huge arms and I started to make friends with them. They introduced me to synthol and I got excited about the results I lost control.
He didnt stop even when his muscles began to solidify. He admits: I couldnt even inject my arms they were full of rocks..
However, he describes how the doctors were able to save his arms. Thank God the doctor told me that they did not have to amputate they could instead remove the synthol rocks which had formed in my arms, he says.
He has now not used the substance for two years and, while he admits hes still tempted by muscle enhancing drugs, he says he wants to achieve his ambitions of being a professional bodybuilder through exercise and diet alone
