GNC, Cellucor C4 Extreme DMMA Class Action Lawsuit

By Mike Holter

C4 Extreme
A federal class action lawsuit claims General Nutrition Centers (“GNC”) and Cullucor Sports Nutrition sell a “dietary supplement” called C4 Extreme that contains a dangerous drug called 1,3 dimethylamylamine (“DMMA) that is synthetic, and not derived from geraniums, as advertised. The class action lawsuit is seeking $5 million in damages for consumers who purchased C4 Extreme thinking they were purchasing a natural dietary supplement.
“Defendants have claimed that C4 Extreme is a dietary ‘supplement’ that contains DMMA which, they contend, is a naturally-occurring substance derived from geranium stems, seeds or geranium oil. This is untrue,” the C4 Extreme class action lawsuit states.
“Studies have concluded there is not DMAA whatsoever in geranium oil, that DMMA is not extracted from geranium oil, and that all DMMA on the market is synthetic. Because DMMA is a wholly synthetic substance, it is not a ‘dietary ingredient’ and C4 Extreme is not, therefore, a ‘dietary supplement’ as those concepts are defined by… the FDA. Therefore, Defendants’ marketing of C4 Extreme as a dietary supplement is false and misleading,” the class action lawsuit continues.
“Defendants’ labeling, marketing and advertising fails to inform consumers that DMAA (a) is not a dietary ingredient; (b) is not a naturally occurring substance or derived from a naturally occurring substance; (c) is synthetic and manufactured in laboratories or similar facilities; (d) is a potentially dangerous central nervous system stimulant; and (e) that using C4 Extreme can cause serious medical harm.”
The Cellucor C4 Extreme DMAA class action lawsuit is brought on behalf of all persons in the United States who purchased C4 Extreme at any time during the past four years. It is seeking damages and injunctive relief necessary to disgorge and/or restore monies received by Defendants as a result of their alleged deceptive conduct.
