My son will sign his national letter of intent papers to play football in college in a few weeks. He is currently 6'3" 195lbs and plays QB. He is starting the off-season lifting and has 4-5 months to put on 10-15 pounds (or more) of muscle. He is currently taking No Xplod before workouts, cell mass after and2x per day. I want to safely help him achieve his goals with proper supplementation. There's so much out there and the local guys at the nutrition stores want to sell us anything/everything they have. What products and regimen would you recommend? Thanks for your help!
