We could not do this without ensuring that our products are safe for athletes to use and therefore we have our products externally validated by a World Class sports doping control laboratory, LGC Sports Science.

We are the first and only brand to receive an evolved accreditation with Informed Sport. This accreditation involves a three-pronged approach across our full portfolio with all raw ingredients being tested, blind testing on final products and unannounced audits of our manufacturing facility.

We go beyond the accreditation standard by screening suppliers, testing incoming raw materials and carrying out checks in the factory. This is in addition to the finished product testing standard used by Informed Sport.

SiS is also ISO 9001:2008UKAS accredited. This means that we have proven that we have stringent policies and risk assessment structures.

We have been supplying elite, regularly tested athletes, national and professional teams for more than 15 years. We have worked with these athletes and teams to ensure that they have the utmost confidence in the robust nature of our systems. We have regular visits by the representatives of these teams to see our banned substances systems and procedures in action.

We understand our responsibility, which is why we put so much effort into ensuring that athletes using our products are safe to use them at every level of sport.
