WASHINGTON — USA Today on Monday morning reported two products marketed as dietary supplements in outlets including Walmart.com and GNC have actually been adulterated with a chemical similar to methamphetamine.
The supplements included Craze, a pre-workout powder sold by Driven Sports, and Gaspari Nutrition's weight loss supplement Detonate.
"These are basically brand-new drugs that are being designed in clandestine laboratories where there's absolutely no guarantee of quality control," Pieter Cohen, an assistant professor at Harvard Medical School and a co-author of the analysis of Craze samples that's being published Monday in the peer-reviewed scientific journal Drug Testing and Analysis, told USA Today.
USA Today reported that Walmart.com and several online retailers had stopped selling Craze in the wake of USA Today's initial investigation into the supplements. Detonate is sold by a variety of online retailers, the paper reported.
