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.
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.
