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."
