Did i get scammed

Creatine beginner question

So i went to gnc and was looking for creatine monohydrate, but the guy sold me on CG5 “creatine + glutamine” and i don’t know if this is actually better. It isn’t a monohydrate and i know monohydrate is the reccomended one, so will this work just as good tho or did i just get fucked over? The guy also told me i don’t have to drink a ton of water with this creatine either.
