How Is It Injected?

Is it injected with a .dll or is it injected by running a .exe?
I will not be able to use this if it is used by a injector and u inject it manually.
I get an error message when injecting .dlls into my gmod and the only way to fix it is by reimaging my .dll files (which cost almost as much as the lifetime purchase for the master package, which is what i want to get).
Thx,

You download a client which is an .exe you insert your ID and Password and inject, open game and you are ready to go
