Yes! When you come to doping things become really tricky! You might not believe it but in some cases even amateurs use doping for extra fast muscle building. If you work with weights, the temptation can be important because you get fast results. This is an immense risk! You can actually overdose from doping substances! Unfortunately, there has been some fatal cases.
On top of that keep in mind countless negative side effects! My advise is to stay away form any form of doping! Be sure you train in a "clean" environment!
