Nutritional supplements are used by top, competitive and amateur athletes. 

An international study funded by the IOC and carried out by the Institute of Biochemistry at the German Sport University Cologne showed that approximately 15 percent of nutritional supplements purchased in 13 different countries contained anabolic substances (mainly prohormones) which were not declared on the packaging. In Germany approximately 11 percent of the nutritional supplements tested contained banned anabolic substances.

A result which leads to uncertainty amongst athletes competing at all levels.

Manufacturers can use the Cologne List to inform their target group (athletes, trainers and sports physicians) about their products and considerably minimise any uncertainties they may have.

The completion of the self-disclosure form and an analysis of the product for anabolic steroids at the Center for Preventive Doping Research at the German Sport University Cologne are requirements for publication on the Cologne List.

The Cologne List is a separate service offered by the Olympic Centre Rhineland which goes above and beyond the basic service of the Olympic Centre. Therefore the cost of the service cannot be borne by the public funding of the Olympic Centre.

The cost of a product entry on the Cologne List® amounts to € 300.00 annually plus the applicable VAT.
