I really hope you are not thinking of shooting steroids into your vein!!!! When you shoot something into a vein, it goes DIRECTLY into your blood stream meaning it goes straight to your heart and straight to your brain. It is meant to be injected under the skin/ into the muscle only– a much more indirect root into the bloodstream. IV (intravenous) injection of steriods is a pretty damn good way to kill yourself. Please learn the proper way to inject yourself before trying it to make certain that you do not make this mistake. By the way, how old are you? How long have you been working out– maybe it is not even time yet for you to start using Anabolic steriods….
