A bodybuilder who modelled himself on the Incredible Hulk risked his life by injecting oil and alcohol into his arms – and almost had both amputated.

Father-of-one Romario Dos Santos Alves, 25, used the potentially lethal cocktail to pump up his biceps to 25in and he now faces a catalogue of serious health issues.

The former bodyguard said using the synthetic filler synthol cost him his sanity and nearly his life as he tried to kill himself when his wife was six months pregnant.

He said his swollen muscles terrify children in his hometown of Caldas Novas in Brazil and they call him a 'beast' and a 'monster'.

Father-of-one Romario Dos Santos Alves, 25, risked his life by injecting oil and alcohol into his arms – and almost had both amputated

'If you take it once there will definitely be a second time - it's addictive,' he said.

'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.'

Mr Alves became obsessed with the drug after moving from his hometown 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.'

He even tricked his wife Marisangela Marinho, 22, (pictured together) into injecting him with the oil in places that he could not reach

He 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.'

He even tricked his wife Marisangela Marinho, 22, into injecting him with the oil in places that he could not reach.

'I told her there was no problem with it - that it left the body after a short time.'

The filler began causing him constant pain and he almost suffered kidney failure due to the toxins in the oil

But after she learned the truth she made it clear that he had to choose between their relationship and the synthol.

'She told me that if I start using synthol again or anything like it she will leave me because of what she went through,' he said.

'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.'

His 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 hospitalised 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 him 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.'

Now Romario's bizarre appearance generates mixed reactions from people in his hometown.

He said: 'One time I was working in a catholic church and a woman came up to me and said that her 12-year-old daughter wouldn't come in because she was afraid of me.

'She said that she thought I was a beast, a monster - I just put my head down and didn't say anything.

He also receives praise and adulation for his incredible physique - which made it even harder for him to kick the addiction, pictured during the early stages of injecting muscle enhancer into his arms and shoulders

But he also receives praise and adulation for his incredible physique - which made it even harder for him to kick the addiction.

'One time when I was working as a bodyguard in a party the girls started to get wasted and were trying to take my shirt off to see my body,' he said.

'Sometimes kids will come up to me and say that I look like the Incredible Hulk and hug me and have their photo taken with me.

'I really like that as I modelled my body on the Incredible Hulk.'

He has not used the substance for two years but other muscle enhancing drugs still tempt him from time to time.

'Two weeks ago I bought a substance called estigor - a horse hormone,' he said.

'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.

'My mind started remembering things that I've gone through and I thought that I couldn't do it - I couldn't give in to temptation again.'

He still has ambitions to become a professional bodybuilder but is committed to staying clean.

'I still feel like taking synthol but I won't take it again. If you take it once there will definitely be a second time - it's addictive,' he said.

'I regret it a lot - my ambition is still to become a bodybuilder but I've got a long way to go.
