ExtenZe is a herbal nutritional supplement claiming to promote "natural male enhancement", a euphemism for penis enlargement.[1] Additionally, television commercials and advertisements claim an "improved" or "arousing" sexual experience. 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 star Ron Jeremy.[2] Former Dallas Cowboys head coach Jimmy Johnson has also appeared in an ExtenZe commercial.[3] ExtenZe makes pills and 2-ounce shots that are sold in over 75,000 retail stores. ExtenZe has been on the market for over 17 years and has sold over 2 billion pills.[citation needed]

Side effects[edit]

ExtenZe rarely has side effects, although they are possibly associated with yohimbe extract. Potential side effects include increased body temperature, increased blood pressure, sweating, increased heart rate, nausea, and upset stomach.[4] 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 staying asleep.[5]

Individuals who are on prescription medication or who suffer from various medical conditions are recommended to consult a medical care provider before consuming ExtenZe. Also, if side effects are experienced, one is advised to interrupt taking the pills and visit a doctor.

Sports and doping[edit]

Both professional football and Olympic athletes are banned from taking ExtenZe because the DHEA in ExtenZe is considered a performance enhancer. To date Viagra has not been banned by these sports agencies. In 2010, 400-meter Olympic gold medalist LaShawn Merritt was banned from competition for taking ExtenZe,[6] which contains dehydroepiandrosterone (DHEA), a steroid that is banned in athletic competition. Merritt apologized, saying that he did not realize that the formulation contained DHEA. Merritt provisionally accepted a two-year ban from competition, although he announced plans to appeal. Sports authorities, however, were not sympathetic:

"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.[7]

Late in 2011, however, his ban ended and he was cleared to compete in the 2012 Olympics [1].


The product is manufactured by BIOTAB Nutraceuticals, Incorporated.[1]


It has been reported that the product website lists DHEA as an ingredient.[8]
