The Pitch: "The once-daily tablet for natural male enhancement"
April 2009. Enzyte is a daily herbal supplement, heavily marketed on TV and the web, that supposedly increases a man's sexual endurance and stamina. According to one analysis we found, this pill contains such exotic herbs as maca root, saw palmetto berry and tribulus terrestris, none of which have been evaluated by the Food and Drug Administration for their effectiveness or long-term safety.
So does the smiling guy on the Enzyte commercials have something to smile about? Among actual users, reviews at Amazon.com and Drugstore.com are decidedly mixed. Although some users say Enzyte does increase their stamina, others complain that the product is worthless. Frustratingly, genuine testimonials about Enzyte's effectiveness are hard to come by. Websites like Herbal-Supplements-Guide.com that disparage Enzyte do so only to tout their own, dubiously effective male-enhancement remedies. It's repeatedly pointed out that Enzyte's claims are based on absolutely no testing data, though some insightful reviewers note that the "placebo effect" can hold a powerful sway over the male libido. (We also found very few comments about Enzyte on reputable bulletin boards.)
On the plus side, one reviewer (who seems to be unaffiliated with Enzyte) points out that Berkeley Premium Nutraceuticals stands by its money-back guarantee. However, he also notes that, once you get your first month's supply of Enzyte, you'll automatically be shipped (and billed for) refills unless you expressly cancel.
Although this has nothing to do with Enzyte's effectiveness per se, it may be helpful to know that Berkeley Nutraceuticals founder Steve Warshak was convicted in February 2008 of federal fraud charges related to the sale of Berkeley products.
According to a Wall Street Journal report, "Federal prosecutors accused the company of bilking customers out of $100 million through a series of deceptive ads, manipulated credit card transactions and refusal to accept returns or cancel orders."

Nayman doesn't have much to say about how (or whether) Enzyte works, but he does point out that this product has a better-than-average money-back guarantee. He warns against ordering the free one-month supply, since this automatically signs you up for paid refills unless you expressly call and cancel. A list of Enzyte ingredients, with descriptions, is helpful.

This article, which appears to have been written by a health professional, points out that Enzyte's effectiveness is not backed up by any clinical studies, and mentions side effects including insomnia, gas, dizziness and constipation.
Review: Enzyte, Editors of eMedTV.com
About 10 users describe their experiences with Enzyte, and the results are overwhelmingly tepid, with an average rating of 2.5 out of five stars. One or two users enthusiastically endorse Enzyte, saying that it gave them increased stamina. But other users say they noticed no change in sexual performance, or only a mild reduction in sensitivity.

Roughly a dozen consumers review Enzyte. A handful of users say the product works as intended, while others say it doesn't work at all. Even one user who gave Enzyte a perfect score of five stars cautions that "this product will have different levels of effectiveness for different people."

This brief article describes the conviction of Steve Warshak, founder of Berkeley Nutraceuticals, for bank fraud and money laundering. However, this legal action has nothing to do with the claimed effectiveness of Enzyte.
Review: Enzyte Founder Guilty of Fraud, Editors of USA Today, Feb. 22, 2008
At first, this article reads like an impartial, balanced critique of Enzyte's effectiveness. However, towards the end it becomes a pitch for another supplement of dubious effectiveness called VigRX Plus. This pattern is repeated in numerous other, seemingly scientific critiques of Enzyte posted on the web.
