I use NO Xplode and I like it, but it's not a mass builder. It's got caffeine, along w/ the NO and it seems to energize me for my workouts. Cellmass, however, (or another good creatine) is what you should be considering more for muscle gain.
Obviously, eating good is important, but supplements can and do help. I actually disagree w/ a good part of what Fyodor replied with (no offense, Fyodor).

Supplements are usually in pill form or in liquid form (after you mix the powder of course)...do you think liquid=mass?.
The idea is not for muscle gain to come directly from "the liquid". There is no mass building caloric value to a pill or drink mix (unless it's protein powder). Supplements trigger different reactions in your body. Some give you energy to go longer and harder, some aid recovery, some promote natural hormone release, etc. At any rate, yes, they can help.

No way you need to be eating LOTS of solid food.
What about milk? Protein shakes? They're not solid and they're among the most valued components in my diet.

No way you need to be eating LOTS of solid food, more than you want to eat even. Eat till you cannot eat anymore, then eat anyway. Lots of CARBS. People put over protein and yes its very important but when you are bulking CARBS are just as important.
He said he wants to gain muscle. Your suggestion is a recipe for turning him into a fat ass. Carbs are important for energy and to make sure you don't go catabolic. Protein is directly responsible for muscle building, however, and is of far greater importance to that task than carbs. Yes, eat complex carbs over simple, but, no, you don't need to eat lots and lots, unless I misunderstood the original question and you do just want to gain mass and not neccessarily muscle.
Eat smartly, not neccessarily in gigantic quantities.
