A Monrovia diet supplement maker that promises its Extenze pills increase penis size is paying $1.75 million in penalties to settle consumer protection law violations.

The Orange County district attorney‘s office says Biotab Nutraceuticals Inc. misled consumers with unsubstantiated advertising claims about some of its supplements, including Extenze.

Biotab has not acknowledged fault or liability but has agreed to terms of an injunction to prevent any future unfair business practices.

Besides the $1.75 million in civil penalties, Biotab must pay restitution to consumers who have not received refunds after filing complaints from 2006 to 2011.

Advertising for Extenze claims that the pills, which cost more than $1 each, are the strongest, most advanced formula available to increase size and enhance sexual desire, pleasure and performance.
