Kirill Tereshin, 21, is known for his huge Popeye-style biceps after undergoing controversial injections but is now suffering from the consequences of his experiments.
Concern was raised after the former soldier, from Russia, posted on Instagram saying his “bazooka arms are about to fall off”.
Disturbing pictures show his biceps with a shocking red and purple discolouring yet he plans to continue injecting himself with a homemade brew based on Synthol, made from olive oil, lidocaine and benzyl alcohol.
Russian media has accused him of trying to become a “freak” as he chases Instagram glory.
SHOCKING: Tereshin’s arms have a red and purple discolouring
“One day abscesses will develop”
Earlier he was warned about paralysis – but a top medic says the threat is graver.
Respected 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.”
DANGER: Top medics fear for his health
He has already injected himself with six litres of this “dangerous liquid” and increased the size of his biceps to 23 inches.
Tereshin had made clear he plans to stop at 27 inches, say 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.”
Tereshin said: “For about a month I was making up to ten injections into each arm every day, using a 20 ml syringe.
“If I had used real Synthol, it would have cost me about 400,000 roubles (£5,000), 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.”
