We stand behind each and every product with our unconditional satisfaction guarantee when purchased through an authorized reseller. Every human body is different, with different needs and tolerances, so no product (natural or otherwise), works perfectly for absolutely everyone. However, thanks to our unique formulation methods and quality ingredients, our products tend to work better, and with fewer side effects, than other products. If they don't work in your particular case, just return them to the place of purchase for a full refund. Some products take two bottles to produce clear results, but our guarantee still stands when purchased through an authorized reseller — complete satisfaction or a full refund. Our motto says it all: "Guaranteed Results, Naturally!"
