Absolutely NOT! There's no need to! However, individuals are free to take our products in for evaluation or testing at their own expense. Dherbs.com is not like any other company. Integrity is our trademark and we would never compromise the integrity of any product. You see, other companies have to test their products because they don't use pure herbs. When you start using standardized products, oxides, and a host of other man-made constituents, then you need testing and rightly so. But not with pure herbs (pure food)! If you doubt the efficacy of any Dherbs.com product, by all means, please take the product in for testing and/or read some of the Testimonials. Believing is seeing (in many respects)!
