25-year-old Brazilian Romario Dos Santos Alves is one of the most infamous synthol abusers. His arms are 25 inches in girth, but according to his doctor, they’ve completely turned to rock.
“I remember the doctor told me that they would need to amputate both arms—they said everything in there, all my muscles, were rock,” Alves said in an interview with Daily Mail. He also exclaims how addictive the substance is, and discourages others from using it.
It looks like he’s realized his mistakes a little too late.
