Bodybuilders in Brazil are risking death by injecting themselves with a potentially lethal cocktail of oil and alcohol to pump up their muscles.

Arlindo de Souza has grown 29in biceps - the biggest in Brazil - after injecting the filler into his body, where it causes appearance of swollen muscles.

But even he admits it can cause dangerous infections. Some users have had their arms amputated. Others have died.

'My friend Paulinho, he passed away from doing these things,' said Mr de Souza.

'I felt his death a lot. He took it, I took it, but he went beyond the limit. I advise no-one to take this oil.

'I've stopped taking it, and other things as well, but there is always that will to start again. But I'm managing to control myself, to this day.'

The oil concoction Mr de Souza injected is believed to contain mostly mineral oil, which is similar to baby oil but unscented, and smaller amounts of alcohol and anaesthetic.

Worryingly, he has said it can easily be bought online or under-the-counter at rogue pharmacies.

And, though he has stopped using and warns others to stay away from it, he says it is continuing to sweep across body-conscious Brazil and South America.

'To get a body like mine, it is very difficult if you are not taking anything. Some people take it but won't admit it,' he said.

'Have you ever seen a guy as big as me claiming it is natural? He is lying, I tell you. At least I tell the truth.

'It stopped for a bit because it was becoming too visible. But they are still using it, only they are using it undercover.'

Injecting site enhancement oils carry the risk of infection and of abscesses developing in the muscle. These abbesses can grow and spread within the tissue.

Some users, when operated on, have been found to have arms full of pus and oil.

Mr de Souza has fears for his own health and has visited a clinic for help. But medics have so far refused to operate because 'he did it to himself'.

Mr de Souza said: 'If I get ill, if my arms burst, that's when I can go and see the doctor. But for me that's normal and something I've accepted.'

Since he began injecting two years ago, he has become the talk of the town, to the horror of his family.

His sister Marineide Gomes de Souza said the family were 'extremely worried' about him but still hoped he would settle down and have a family.

'He is a good person, not a bad person. He is really friendly and does lots of favours for people,' she said.

'But there are some people who make fun of him. There are some people who find it interesting. And there are some people who think he is from another planet.'
