A Russian bodybuilder known online as the “Russian Popeye” may now lose both arms.
Doctors say his biceps are severely infected after years of injecting them with synthol. The injections caused his arms to swell to a cartoon-like size, gaining him viral attention.
The man, 29-year-old Kirill Tereshin, began injecting petroleum jelly and synthol in 2017. His arms ballooned to 24 inches, earning him the nickname due to their Popeye-like look.
Tereshin shared shocking footage showing his bicep had “burst,” revealing rotting tissue underneath.
Doctors now say he may need both arms amputated if the infections cannot be controlled.
Doctors Say Time Is Running Out
Russian media reports that Tereshin needs multiple skin graft surgeries to repair the damage.
However, doctors say they cannot operate until the infection is fully under control. They warned that time is running out to stabilize his condition.

His treatment would require vascular, reconstructive, and plastic surgeons working together.
The toxic chemicals caused severe tissue fibrosis and necrosis in his arms. This means large portions of muscle have died and can no longer heal naturally.
Tereshin previously underwent surgery in 2019 to remove some damaged tissue. But the current infection is reportedly much worse and spreading quickly.
He Admits Regret, Calls It a “Stupid” Mistake
The former Russian soldier has spoken about his regret over the injections.
He admitted he was chasing online fame when he started injecting synthol. He has called it a “stupid decision” and said he wishes he had never done it.
Doctors had warned him years ago that he could die if the substance wasn’t removed. He ignored many warnings and continued to post viral videos showing his huge arms.
Now, experts say amputation may be his only chance of survival.
From Viral Fame to Medical Crisis
Tereshin became a social media sensation because of his bizarre appearance.

People around the world shared photos and videos of his balloon-like arms. Some thought it was fake, while others believed it was a dangerous trend.
His case is now used by doctors to warn young people about synthol. Experts say the injections do not build muscle and only create fake swelling.
The chemicals do not dissolve and instead stay trapped inside muscle tissue. Over time, this often causes infection, nerve damage, or tissue death.
Doctors say they will try to save Tereshin’s arms if the infection stabilizes. But they also warn that amputation is a likely outcome at this stage.
Tereshin has not announced whether he plans to continue treatment.
Many online users have reacted with sympathy, while others see it as a cautionary tale.
His journey from viral fame to medical crisis shows how dangerous these trends can be.
