Websites selling the product make several more detailed claims, including acquiring a "larger penis". Their enlarging effects are described as "temporary" while under the use of ExtenZe. Early infomercials featured a studio audience and porn starRon Jeremy.[3] Former Dallas Cowboys and Miami Hurricaneshead coachJimmy Johnson has also appeared in an ExtenZe commercial.[4] ExtenZe makes pills and 2-ounce shots that are sold in over 75,000 retail stores.
The product is manufactured by BIOTAB Nutraceuticals, Inc.,[1] and marketed by Maximizer Health Products.
False advertising and side effects
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.[5]
ExtenZe maker, Biotab Nutraceuticals, Inc., settled a class action false advertising lawsuit in 2010 for $6 million.[2] The plaintiffs claimed that ExtenZe made deceptive marketing claims about the product enlarging a man’s penis despite lacking credible scientific evidence to support these claims.
ExtenZe's side effects are possibly associated with yohimbe extract. Potential side effects include increased body temperature, increased blood pressure, sweating, increased heart rate, nausea, and upset stomach. 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.[6]
In 2018, ExtenZe came under scrutiny of the FDA as a certain production lot of ExtenZe Plus was found to contain sildenafil, which is the active ingredient in Viagra.[7]
"Any professional athlete in this sport knows that they are solely responsible for anything that goes into their bodies. For Mr. Merritt to claim inadvertent use of a banned substance due to the ingestion of over-the-counter supplements brings shame to himself and his teammates. 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.[10]
Late in 2011, however, his ban ended and he was cleared to compete in the 2012 Olympics.[11]
Although the company claims that the product is completely natural, FDA testing confirmed that one of ExtenZe's variants, ExtenZe Plus, contains traces of sildenafil, a prescription medicine used to treat erectile dysfunction.[7]
