Tested and Certified For Banned Substances

Xendurance was the first US Sports Nutrition company to use LGC Sport Science's certification programs: INFORMED CHOICE & INFORMED SPORT.

Extreme Endurance is “Tested For Banned Substances" by LGC, and has received certification by both & INFORMED-SPORT and INFORMED-CHOICE. LGC Sport Science is one of the world's premier independent drug surveillance laboratories, providing unrivaled and internationally trusted expertise in doping control for sports. LGC has been testing supplements/ingredients for banned substances since 2002 and has a institutional history dating back to 1842.

The LGC laboratory is ISO Certified and accredited for forensic testing and meets or exceeds World Anti-Doping Agency standards and requirements. Tests performed on our products use state-of-the-art gas chromatography, liquid chromatography, and mass spectrometric detection. These test results can detect substances down to ten parts per billion for steroids and 100 parts per billion for stimulants. Testing is very expensive, but the world's best athletes and professional sports teams demand the safest, drug-free nutritional products.

Tested endurance supplements, and batch samples are catalogued and retained for the product shelf life. If an athlete who has been using Xendurance products tests positive for banned substances, these sealed batch samples will be made available for a third party, independent test, to prove the positive test was NOT due to our products.

What is INFORMED-CHOICE & INFORMED SPORT?

INFORMED-CHOICE & INFORMED-SPORT (EU Certification) is a supplement testing and certification program assuring athletes that products carrying these marks have been regularly tested for prohibited substances. Responsible supplement companies have made INFORMED-CHOICE & INFORMED SPORT part of their existing quality assurance systems to ensure their products are safe for athletes to use.

Some supplement products from less meticulous manufacturers have tested positive with low levels of steroids and stimulants prohibited by WADA and other sporting bodies. The INFORMED-CHOICE & INFORMED SPORT program aims to work closely with supplement manufacturers and suppliers by providing high quality, analytical testing to minimize the incidence of banned contaminants finding their way into sport.

INFORMED-CHOICE & INFORMED-SPORT were established in 2007 by LGC Sport Science when it became clear that there was a need for a comprehensive certification program which not only tested products for banned substances, but were manufactured in qualified facilities meeting FDA GMP standards.

Athletes who see the INFORMED-CHOICE & INFORMED-SPORT logo on a product or brochure or any media of any type must review the lot# on the product pouch and confirm that particular lot# is noted as tested and certified in LGC Sport Science. If the lot# is listed under INFORMED SPORT and INFORMED CHOICE and shown to be certified, then they can be confident it has undergone a rigorous screening program for banned substances and is safe to use. If you do not see the lot# as certified under LGC Sport Science, please contact Xendurance by email for assistance prior to use.
