A laboratory analysis conducted by the Center for Preventive Doping Research (CePreDo) at the German Sport University Cologne is absolutely mandatory for a product listing on Cologne List®. The CePreDo analyzes products for selected anabolic-androgenic steroids and stimulants. Only products that have successfully passed a label check at the CePreDo will be analyzed. Analysis reports from the CePreDo may only be published on Cologne List® and nowhere else.

Companies also have the possibility of publishing analysis reports from other laboratories under the "Company's Comments on the Product" section. However, reports from other laboratories do not replace laboratory analysis at the CePreDo, which is absolutely mandatory for each product.

Conditions for laboratory analysis of a product:

The laboratory requires one unit of consumption of your product in its original packaging. If this contains less than 30 grams, please submit additional units with the same batch number. Products consisting of several subsamples require separate treatment. The laboratory also requires a written analysis request. To facilitate things, please submit the analysis request together with the samples, marked to the attention of Dr. Ute Mareck.


EUR 450 excluding VAT for a laboratory analysis for anabolic-androgenic steroids and stimulants including a label check. Should your product fail to pass the label check, no charge will be issued.
