Injector and VAC question

Hi, so I've made myself an injector but I ain't got $10 (in fact never had at once xD ) to spend on a CS:GO account to test it. What actually makes an injector detectable by VAC? I've tried to avoid the word "injector" and "inject", and most of the variables names are some weird shit strings. The thing is I googled for a bit (Yes I know how to google) and some people say that CreateRemoteThread is detectable, but I don't know any other injection method that that...

So... is my injector detectable because of that?

Thanks.
