"One of the biggest risks you face if you dabble in insulin abuse is that a hypoglycemic reaction (low blood sugar) can result in death, coma, brain damage or an epileptic fit. I read a case report of a 30-year-old bodybuilder who injected a high dose of insulin before a competition and went into a coma with seizures. He did not respond to intravenous push dextrose or a dextrose drip. He ended up on life support in an intensive-care unit. Darwin award.

"Diabetics...take insulin to stay alive, and have to live with the risks. Most of us don’t."
