Another product called Extenze also hit the market in the mid 2000's. Instead of Bob, former Dallas Cowboy's football coach Jimmy Johnson gave the pep talk to men at home on the bench. In an ad, Johnson tells viewers, "Go long with Extenze, I do!"
Both products promised to make a certain part of a man's body larger and both companies ended up with legal troubles over it.
Enzyte's founder Steve Warshak was busted for fraud and other charges. He was ordered to forfeit $500 million in assets and is currently serving a 25-year prison sentence. | Read the Settlement
Extenze settled a civil lawsuit. The company agreed to set aside $6 million in cash for refunds and another $6 million in Nascar licensed merchandise offered to customers with the Extenze logo on it.
Doctor Todd Waldmann at Idaho Urologic Institute says there's nothing offered over-the-counter or by prescription that will change genetics.
"If you know the answer to that let me know and we'll both get rich," Dr. Waldmann told KBOI 2News' Brian Morrin.
Despite the legal troubles, you can still buy Enzyte and Extenze although both companies have toned down their claims.
Enzyte website says the product can "help erectile function, promote critical blood flow, and guard against nutrient deficiencies."
But on the very same website, the company admits "the statements have not been evaluated by the Food and Drug Administration."
Extenze now claims its product "Enhances desire, power, pleasure and performance and improves your overall sex life."
Same products, different claims but same assessment from the medical community.
"There's no concrete scientific data that they accomplish anything," Dr. Waldmann said.
Not only are the products unproven, Extenze may be dangerous. It has a compound called Yohimbe which brings risks such as heart attack, stroke and fast heart rate.
The Yohimbe extract can also interact with your prescriptions.
"There's a whole laundry list of medications that interact with Yohimbe itself," Waldmann said.
Enzyte and Extenze claim to be natural products, but like many other supplements, that doesn't mean they're safe.
"There's no onus on producers to prove they're safe first," Dr. Waldmann said.
