I use it every day (or at least most days if I don't forget it haha). You want to get your creatine pretty much every day. I say you also want to get your betaine at least almost every day (daily ideally), so I try to take IntraMax every day to get my creatine and betaine every day. I also use it as a sort of small shake type product sometimes; taking it between meals on rest days, or taking it with a snack or small meal that maybe doesn't have ideal/optimal protein/leucine content, so it can help a bit there too. There's not really a "wrong" way to do it really, but daily use would be "ideal" if anything.
