If he is looking for 7-10lbs of mass that he will keep, why not point him in the direction of EQ, IMO the quality of gains are much better than deca. Maybe EQ - Prop - winny, or Test - EQ cycle, or maybe even EQ - Prop - Fina, all very good cycles to gain 10lbs and keep it, all while getting strong and vascular IMO.
