The market of nutritional supplements is very dynamic and heterogeneous. Supplements may be accidentally contaminated during the production process or intentionally mixed with prohibited substances by the manufacturer. Although only a relatively small number of products are actually contaminated (see 2004 IOC study), they present a serious risk to athletes and may even discredit the entire nutritional supplement industry.

Cologne List®, therefore, provides athletes and manufacturers with an independent service platform providing transparent information in the interest of both parties.

The necessary laboratory analysis of SuddenRush X-Strong for anabolic steroids and stimulants was provided without objections on 13th July 2020.
