Karim had been training for a few years and reached a plateau – he wasn't getting results and wanted to get bigger. At the gym, he had asked the bigger boys and received tips on how to get his hands on anabolic steroids. He made contact with a dealer from whom he later bought the drugs. By the age of 20, he had taken his first course of treatment.
"I got results, but it wasn't worth it," he says.
Large availability of doping substances
According to the police, there are plenty of doping substances in Sweden and the supply is large. A report from Swedish Customs shows that a large part of the sale of doping substances takes place online. It is also not uncommon for doping substances to be smuggled into the country.
Last year, Swedish Customs made 617 seizures and stopped 128,534 doping substances, according to figures obtained by SVT Sörmland. China, Russia, Bulgaria and Spain are the most common countries sending doping substances to Sweden.
Exercisers dope themselves
Area police officer Amanda Shehadeh Karlsson in Eskilstuna has been involved in several efforts at gyms and she says that it has become increasingly common for strength-trained exercisers to be caught having doped themselves.
"There is an incredibly large number of unreported cases, there is much more than you think. Even among people you don't think get doped," she says.
