Theoritically you can inject whatever muscle you like but in true world application. It's a very bad idea and practice. Steroids and all the drugs that have to be injected IM, are to be injected deeply into big muscles like the glutes, the quads and the ventroglutes. Keep in mind that the glutes and the ventroglutes are the best sites for injecting since there aren't many nerves and many vains (in contrast to the quads).
The only thing that comes close IMO is Test Suspension. You inject and then a couple hours later you workout. Not having an ester allows it to enter the bloodstream very rapidly. It's probably all in my head, and I haven't done it in quite some time, but I used to site inject suspension with slin pins all the time and swear it would help that muscle grow faster. Again, could just be a psychological thing.
