List of illegal potency enhancers

At the Danish Medicines Agency, we routinely analyse products that we suspect contain active pharmaceutical ingredients which are not declared in the product information. We are also informed about such products through our cooperation with the drug regulatory authorities in other countries.

Through this work, we have been made aware of a number of illegal potency-enhancing products which all contain active substances appearing neither from the product declaration nor the package. The products, which are often sold on the internet, can be dangerous to health, and we therefore warn consumers against using them.
