Synthetic oils, also known as site enhancement oils, aren’t anything new in the body building community. In 2015, Romario Dos Santos Alves, a former bodyguard and bodybuilder from Brazil, made news when he admitted that his habit of injecting synthol — a popular synthetic oil/anesthesia combination — successfully inflated his muscles but put his life at risk.
In another case, a 25-year-old weightlifter who injected coconut oil into his biceps wound up in the hospital, as doctors reported in the British Medical Journal in 2015. Like most people who dabble in oil injections, whether synthetic or not, this person was trying to augment the curve of his muscles. He turned up at the hospital, the paper’s authors wrote, agitated and sweating profusely because he was suffering from pain and a loss of function in his right arm.
