Below is a collection of articles and information referring to numerous cases where defectors from a variety of backgrounds have charged human experimentation is taking place on a massive scale within N. Korea.

AHN MYUNG CHUL, NORTH KOREAN DEFECTOR (Translation):
Everyone knows about chemical weapons testing. I saw political prisoners being transported. My commanding officer said, "They are the people you are going to guard for ten years. If they attempt to escape or resist you can kill them. Several of them will go for human experimentation. If you help them escape you will share their fate."

"An Myong-chol heard about experiments on living people. He learned that Gulag doctors conduct experiments very much like those perpetrated by the Japanese Army's infamous 731st Unit and by Nazi death camp doctors... Mr. An said, however, he heard "hundreds" of accounts of experiments on living humans from doctors as he drove them to and from duty or drove them to the scene of accidents."
“Each military medical officer had conducted at least 50 experiments on living people," said Mr. An. "I heard their brave stories many times, how they opened up some hapless inmate free from medical flaw and cut out his liver or some other organ. So common was knowledge of these practices that camp guards universally believe that medical experiments create most of the camp's numerous cripples, many of whom are missing arms or legs."
"Pak Nam: I've heard they throw people live into boiling water in a big pot. When they're boiled, they strip off the fat and render it like pork fat. I heard Hitler gathered human fat in World War II and used the oil to make cosmetics. I think that's how the 3rd Bureau uses it."
