protein is good, but he may want to include some mass related powders for the extra calories along with the protein, there are various ones out there ex. cytogainer, extreme mass. Also i think in terms of creatine a great blend is Dark Matter by MHP post work outs and further supplementation through creatine ethyl ester the next day (CEE made by Cutting Edge labs is a cheap and effective one) Obviously make sure his protein intake is high and the mass gaining products should help with adding needed additional calories to ensure a surplus. Pick your fav N.O. product, thats a personal preference, I like Dark Rage, and you may also want to buy some bulk arginine ethyl ester to mix in with your daily protein shakes, it doesnt taste great but bulk arginine ethy ester powder will help keep you pumped all day recover faster. Just my two cents
