Bannded Substance Free

GNC is committed to providing Sports Nutrition products that are free of banned substances. As part of that commitment, GNC clearly labels products that have undergone an independent testing process to confirm the product's Banned Substance Free status as defined by the World Anti-Doping Agency.

You can find GNC products that have been tested for banned substances by looking for either the "Banned Substance Free" or "Informed Choice" logos on the product’s packaging.

GNC products that feature one of these logos have been tested for banned substances by HFL Sport Science—an independent, world-class anti-doping lab—and have been found to be free of banned substances. This means that GNC products bearing these icons have been tested for more than 145 banned substances on the 2012 World Anti-Doping Agency (WADA) Prohibited List.

What are banned substances?

The World Anti-Doping Agency (WADA), along with many major sporting leagues, maintains lists of substances and technologies that are banned in sports nutrition products due to their performance-enhancing effects that could be used to provide an unfair advantage.

To see the WADA Prohibited List, go to www.wada-ama.org and click on the Prohibited List link.

How does GNC guarantee that their products are free of banned substances?

GNC has teamed up with HFL Sport Science, an internationally recognized, independent and accredited laboratory that provides high-quality testing for nutritional supplements.

HFL Sport Science has more than 50 years experience in the science of sports testing and is accredited to ISO 17025—an international testing laboratory standard. HFL has experience testing within the framework of the World Anti-Doping Agency and has the testing capability for the analysis of more than 145 substances that are considered prohibited.

Does GNC test for every banned substance on the WADA list? If no, why not?

The WADA Prohibited List is specifically designed for urine analysis and refers to substances found in urine (i.e., after the substance has passed through the body). The body may convert some or all of the substance to other compounds as it moves through the body’s system.

Furthermore, not all of the substances on the WADA Prohibited List are able to be present in a supplement product. When analyzing a supplement for contaminants, the Prohibited List is unable to act as a checklist for all prohibited substances against which products should be screened—meaning that supplement analysis cannot guard against contamination of untried, untested and unknown designer drugs.

Although it is not possible to test for all substances on the WADA Prohibited List, HFL’s experience in testing over 30,000 samples and its close relationship with the WADA community has helped to identify a list of banned substances that will maintain product integrity.

Does HFL Certification mean that the product in question complies with my league or organization’s testing policies?

Not necessarily. You should always check the rules and regulations of the league or organization with which you must be compliant since its list of banned substances may differ from the substances tested by GNC.
