An analysis published in the peer-reviewed scientific journal Drug Testing and Analysis today has detected a highly addictive, illegal stimulant chemical in the pre-workout supplements Craze, from New York-based Driven Sports, and Detonate, a weight loss pill from Gaspari Nutrition.
The chemical has a similar structure to methamphetamine, Pieter Cohen, an assistant professor at Harvard Medical School and analysis co-author, told USA Today. This isn't the first time illegal substances have been found in Craze. In June 2012, the U.S. Anti-Doping Agency (USADA) found several prohibited stimulants in the product, including amphetamines and similar compounds
USADA listed craze as a "High Risk Dietary Supplement," and many retailers, including Walmart.com and Bodybuilding.com took the product off their online storefronts. Driven Sports and Gaspari Nutrition have yet to comment on the latest findings.
