Methamphetamine-Like Compound Found In Popular Workout Supplement

A study published on October 14, 2013 (Cohen, Drug Test Analysis 2013) reports that the popular pre-workout energy supplement Craze (Driven Sports) has been found to contain the banned methamphetamine – like compound, N, á-diethylphenylethylamine.

N, á-diethylphenylethylamine has not been studied in humans and its adverse effects are not known, but as a chemical analog of methamphetamine, it is thought to pose similar risks, including heart attack, stroke, and the potential for addiction.

The compound was discovered in three samples of the supplement, taken from three separate lots. These samples were found to contain over 20 mg of N, á-diethylphenylethylamine per serving, an amount which "strongly suggests that this is not an accidental contamination from the manufacturing process," according to lead author of the study, Dr. Pieter Cohen of Harvard Medical School.

Craze is promoted as "performance fuel," that "provides the ultimate in pre-workout power," and is sold throughout the U.S. online and in retail stores. Two of the samples tested were obtained from U.S. supplement retailers GNC and The Natural Health Shoppe, and one was obtained from European online retailer

The supplement is labeled as containing N,N-diethyl-phenylethylamine derived from endangered dendrobium orchids; however, there is no evidence that orchids contain this compound. The banned methamphetamine – like compound found in the supplement was not listed on the label.

Craze has been found to contain other illegal stimulants in the past. Samples tested by the U.S. Anti-Doping Agency (USADA) in 2012 were found to contain amphetamine and amphetamine related compounds. Driven Sports, however, maintains that its own testing shows the supplement does not contain these substances.

According to an investigative report by U.S.A. Today, the researchers also found N, á-diethylphenylethylamine in weight loss supplement Detonate (Gaspari Nutrition).
