Max Muscle protein is just some whey protein right ?
If so, using cell mass which contains creatine and whey protein is a good combo. You might have some initial weight gain using this products because as I mentiond Cell mass contains creatine which adds some water weight when you start taking it. Don't worry about this water weight because you will lose it gradually as you stop taking cell mass.
Gaining and losing weight depends on how much calories you eat. So calculate your calories so you can check if you're eating too much.
I think it would've been cheaper if you just got regular creatine instead of cell mass.. but I don't want to get into that.
