Craze, a sports supplement marketed to bodybuilders, contains a chemical compound similar to the illegal drug methamphetamine, according to a study published in the peer-reviewed Drug Testing and Analysis journal. The substance, called N,alpha-diethylphenylethylamine or N,a-DEPEA, has never been studied in humans, according to Dr. Pieter Cohen, an assistant professor of medicine at Harvard Medical School and lead author of the study.
In July, USA Today published an investigative piece on supplement designer Matt Cahill, "a convicted felon who has a history of selling risky dietary supplements, including products with ingredients linked to severe liver injury and at least one death," the newspaper says.
Rob Riches claims this is the reason he failed a drug test, losing him a British national championship.
