A covert doping sabotage is entirely possible, according to unique tests carried out in Cologne.
SVT's "Document From the outside" reveals the groundbreaking tests, which indicate that athletes may have been misjudged during the course of history.
Anabolic effect via carrier substance
At forensic medicine in Cologne, the subjects were given doping agents via the skin.
The researchers decided on four different substances, all of which have an anabolic effect.
They are muscle-building and highly effective preparations that are usually taken in tablet form or injected into the body.
Through a light touch of the skin, one could transfer sufficient amounts of banned substances to then be detected in doping tests.
The researchers also added a carrier substance that would cause the steroids to be absorbed through the skin.
It acts as a taxi for the doping agent on its way into the body.
Once there, the anabolic substance spreads.
All urine samples positive
The first analysis of the urine samples indicated that all twelve subjects would be strongly suspected of doping.
On the arm, on the back of the hand and in the palm as well as in the neck.
Wherever the dopant had been applied to the skin, it could be detected in the urine.
These breathtaking analytical results could thus turn the fight against doping upside down.
In the documentary "Involuntarily doped" you get to know more about the experiments, as well as take part in several described cases that illustrate the sport's dilemma when it comes to doping, guilt and innocence.
Australian swimmer Shayna Jack and German athletics profile Dieter Baumann are two of the profiles that tell their stories.
"Called to kill me"
World Cup medalist Shayna Jack tested positive for the substance Ligandrol, but she claims that the substance entered her system through contamination and has denied that she deliberately took the drug.
She is appealing the verdict that keeps her away from swimming.
Shayna Jack was suspended for four years.
- I have been asked to take my own life, because people think I doped myself.
It hurts so much that people question who I am.
I did not want to be there anymore, says a crying Shayna Jack in front of the camera.
