Straight from the Texas Attorney General RE: BioPerformance

"The defendants' dramatic markup on their worthless product, coupled with their downline marketing strategy, indicate they were organizing an elaborate, illegal, and unsustainable pyramid scheme."

BioPerformance ordered to return more than $7 million to victims of pyramid scheme

AUSTIN - Texas Attorney General Greg Abbott today stopped a Dallas-based pyramid scheme from illegally marketing the so-called "top secret gas pill" that it falsely claimed would increase fuel efficiency in automobiles. The Attorney General's settlement with BioPerformance and its owners, Lowell Mims and Gustavo Romero, prevents the defendants from continuing to deceptively market their products and ends the State's eight-month legal action against the company.
