ExtenZe

ExtenZe is an herbal nutritional supplement claiming to promote "natural male enhancement", a euphemism for penis enlargement.

In 2006, ExtenZe agreed to pay the Orange County, California, district attorney's office $300,000 in civil penalties for unfair business practices and false advertising.

Susan Kang Schroeder of the DA's office said the company could not back up its claim that the pills caused users' penises to grow by 27%.

After several customers in Laguna Beach, California complained to the Better Business Bureau that ExtenZe was making them sick, the district attorney investigated.

Other side effects can include aggression, pounding heart, restlessness, fever, feeling like fainting, hallucinations, muscle twitches or spasms, abnormal behavior, severe headache, bruising easily, shortness of breath, blurred vision, seizures, ringing in the ears, chest pain, confusion, loss of appetite, weight loss, vomiting, insomnia, mild skin rash, nervousness, cold feeling in the feet or hands, tingling or numbness in the feet or hands and difficulty when sleeping.

Thanks to his selfish actions, he has done damage to our efforts to fight the plague of performance-enhancing drugs in our sport," USA Track and Field CEO Doug Logan said in a press release.
