In 1977 he was appointed director of the Institute of Biochemistry at the Sports University in Cologne.

In 1972 Donike has developed a complete analytical method for the detection of doping for the Olympic Games. He pointed, for example, the Olympic gold medalist in Seoul in 1988 in the 100 m sprint, Ben Johnson, the banned substance Stanozolol after.

Donike and his colleague Johann Zimmermann at the Institute of Biochemistry at the Sport University in Cologne found in the early 1980s that synthetic testosterone in the human body is degraded more slowly than the body's own testosterone to epitestosterone the degradation product. So they laid the basis for tests of the T / E ratio, which are carried out in international competitions since 1982.

Allegations athletes were to advise on the drug-taking in the mirror (13/ 1990) publicized. Was founded in 1995 at the German Sport University Cologne, the Manfred Donike Institute for Doping Analysis eV.
