Brazilian model who wanted to look like the Incredible Hulk risked his life by injecting oil into his arms.
Romario Dos Santos Alves, 25, turned to a cocktail of oil, painkillers and alcohol to pump up his biceps - with astounding results.
Now the former bodyguard terrifies children with his super-sized muscles and is facing a catalog of serious health issues.
The married dad-of-one says his experiences of using the synthetic filler synthol cost him his sanity and nearly his life and he was even scheduled to have one of his arms amputated.
Romario said: "If you take it once there will definitely be a second time - it's addictive.
"I remember the doctor told me that they would need to amputate both arms - they said everything in there, all my muscles, were rock.
"I want other people to see the dangers, I could have died all because I wanted bigger muscles. It's just not worth it."
Romario became obsessed with the drug after moving from his hometown of Caldas Novas to Goiania in Brazil three years ago.
He said: "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."
Romario began to find ever more dangerous ways of injecting himself with the oil.
"My muscles started to solidify and I couldn't even inject my arms - they were full of rocks," he added.
"I decided the only thing I could do was buy specialist needles to inject.
"The kind of needles used on bulls - there are no stronger needles around - I know it seems stupid but I had to get my synthol fix."
"That was the hardest part of our life because I had depression and I was removed from my job because I tried to kill myself."
Romario's biceps had swollen to an incredible 25 inches but reactions from members of the public meant that his mental health deteriorated.
He said: "I was hospitalized in a clinic and my wife was six months pregnant - it was just me and her, no friends or family.
"I decided to fix my ways and I never again wanted to take any drugs, we went through a really hard time and almost starved."
Soon the filler began causing Romario constant pain and he almost suffered kidney failure due to the toxins in the oil.
And he was told by a doctor that his only course of action would be to have one of his arms amputated.
"My wife was crying when I left at 5am to go to the hospital for the procedure," he added.
"I remember the doctor told me that they would need to amputate both arms. They said everything in there, all my muscles, were rock.
"It was either that or cut all of my muscles out.
"And then 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."
Romario has not used the substance for two years but other muscle enhancing drugs still tempt him from time to time.
He added: "Two weeks ago I bought a substance called estigor - a horse hormone.
"I put the needle in my chest and sucked in the air to see if I got a vein but nothing came out. I froze and started to sweat.
He still has ambitions to become a professional bodybuilder but is committed to staying clean.
"I regret it a lot - my ambition is still to become a bodybuilder but I've got a long way to go. I know I will achieve it though."
