Xerisan claims that “boosting metabolism is a scientifically proven method for losing weight and Xerisan can do exactly that.” They claim you can “eat every food you love and still lose weight.” The main ingredients are synephrine, phaseolus vulgaris, chromium picolinate, and calcium pyrovate. The research they site claims it acts as a carb blocker, and then they include ingredients to speed up the metabolism.
Xerisan does use some of the ingredients required to back up their claims to a degree. For example, phaseolus vulgaris has been popularly used as a carb blocker. Likewise, synephrine has been used by many companies to replace ephedra and speed up the metabolism promoting greater weight loss potential.
Xerisan may use some descent ingredients, but they don’t provide nearly the dosage required for the product to actually be effective. Moreover, synephrine, a cousin of ephedra, has been connected to a higher risk of ischemic stroke in some individuals. They offer the bare minimum in terms of money back guarantees. They offer a 30 day money back guarantee, but you have to call them to get a return authorization number. Without that number, whether you return it on time or not, they will not accept your return or issue a refund. They make quite a few claims about their product being “scientifically proven.” But the fact is there are no studies to back up Xerisan being a high powered product. There are a few studies on some of the ingredients that support the fact that those ingredients in the right amount will promote gradual weight loss. But when Xerisan was put through an actual clinical trial, users of Xerisan lost 1.5 pounds in 10 weeks while the placebo group lost an average of 2.5 pounds.
Xerisan tries to promote themselves as the best weight loss product out there. But when it came right down to it and clinical studies were conducted, they did not stand up to the challenge. In fact, Xerisan users lost less than the placebo group, which is at best laughable. Their return policy is skimpy, and I would not waste anything on them.
