A popular and controversial sports supplement widely sold in the USA and other countries is secretly spiked with a chemical similar to methamphetamine that appears to have its origins as an illicit designer recreational drug, according to new tests by scientists in the USA and South Korea.
The test results on samples of Craze, a pre-workout powder made by New York-based Driven Sports and marketed as containing only natural ingredients, raise significant health and regulatory concerns, the researchers said.
The U.S. researchers also said they found the same methamphetamine-like chemical in another supplement, Detonate, which is sold as an all-natural weight loss pill by another company: Gaspari Nutrition.
Craze, which is marketed as giving "unrelenting energy and focus" in workouts, was named 2012's "New Supplement of the Year" by Bodybuilding.com. A USA TODAY investigation published in July reported on other tests detecting amphetamine-like compounds in Craze.
While Walmart.com and several online retailers have stopped selling Craze in the wake of USA TODAY's investigation, the product has continued to be sold elsewhere online and in GNC stores. In recent weeks, Driven Sports' website, which offers Craze for sale, has said the product is out of stock. Detonate is sold by a variety of online retailers.
The researchers, from the National Forensic Service in South Korea and the National Institute for Public Health and the Environment in the Netherlands, noted that the compound found in Craze was the same as that found in a crystalline powder seized by narcotics agents in December 2011 as a suspected illicit designer drug.http://www.usatoday.com/story/news/nation/2013/10/14/tests-of-supplements-craze-and-detonate-find-methamphetamine-like-compound/2968041/
