LGC is a world-renowned sports doping control and research laboratory, with over 50 years of expertise in anti-doping in sport. LGC has published over 300 scientific papers on methods for detection of trace levels of substances that are prohibited in sport and has over 450 man-years of research into doping control.

LGC has been testing supplements and ingredients on behalf of reputable manufacturers and suppliers for over 10 years, and having tested over 50,000 samples during this time. LGC has also carried out a number of research studies to explore the prevalence of contamination with prohibited substances in products and ingredients. LGC's research into supplements and contamination also includes several administration studies to investigate the levels of prohibited substances that could cause an athlete to fail a doping test. These have been published in peer reviewed scientific journals.

All testing methods used for a range of substances from these categories have been validated and accredited to the ISO 17025 standard in supplements and ingredients, in each of the relevant matrices: powders, bars, liquids, capsules, tablets, etc., with defined method capabilities/reporting limits. LGC Fordham has held this accreditation since 2003, granted by UKAS (United Kingdom Accreditation Service), while LGC Lexington gained its accreditation from A2LA (American Association for Laboratory Accreditation, see certificate no. 3244.01) in 2012 shortly after opening.
