An ex-soldier branded a 'freak' after injecting his body with a homemade muscle-building brew has been warned he faces his arms may have to be amputated.

Russian national Kirill Tereshin has gained notoriety for his Popeye-style biceps after using chemicals to bulk up his muscles, reports the Mirror.

The 21-year-old sparked concerns for his wellbeing on Instagram when he posted his ‘bazooka arms are about to fall off’.

Despite disturbing images that show his biceps with a red and purple discolouring, Kirill said he plans to continue injecting himself with the homemade potion.

The brew is based on Synthol, made from olive oil, lidocaine and benzyl alcohol.

Russian media have reportedly accused him to trying to become a 'freak' as he tries to chase Instagram glory.

Kirill has previously been warned about paralysis but now a top medic says the threat is even graver.

Russian doctor Professor Evgeny Lilin, said: ‘Not immediately but he very likely faces amputation in the future.

‘One day abscesses will develop, then inflammation and he (will be at risk of) a stroke.

‘The bad thing is that already-injected Synthol or its equivalent will remain in his muscles for the next five to seven years, even if he stops adding more now.’

Kirill is said to have already injected himself with six litres of this ‘dangerous liquid’ and increased the size of his biceps to 23 inches.

The former soldier had made clear he plans to stop at 27 inches, according to reports.

He then plans to ‘improve’ his back, chest and shoulders.

‘I would like to get more than one million subscribers on Instagram and to stop working,’ he said, adding that he was considering an offer to become a porn star.

However since the shocked reaction to his pictures he took down his social media sites.

Another doctor said: ‘Inside the arms of this man there are already pathologically changed tissues that looks like jelly with insertions.

‘They are aseptic or inflammatory so far but these are abscesses.

‘They consist either of oil or blood from the damaged vessels.

‘They can’t be removed.’

Kirill said: ‘For about a month I was making up to ten injections into each arm every day, using a 20ml syringe.

‘If I had used real Synthol, it would have cost me about 400,000 roubles (£5k), but as I made it myself, I spent only about 4,000 roubles (about £50).

‘I did not feel any discomfort in my arms when I was doing it.... my body got used to it.

‘Within a month I got 106,000 subcribers in my Instagram. I love to be recognisable.’
