GNC AMP Mass XXX is designed for athletes focused on significant muscle gain and recovery, offering a balanced mix of proteins (whey, casein, soy), carbohydrates, and performance enhancers like creatine and HMB. With 50g of protein, 130g of carbohydrates, and 6g of fat per serving, this product provides 800 calories, making it an excellent choice for intense bulking phases. The addition of Tri-MG Infusion™ for enhanced muscle maintenance and micronized amino acids for better absorption adds to its effectiveness, making it a well-rounded choice for serious athletes despite its higher price point.
Rival Clean Gainer, however, stands out for its remarkable value. With 30g of protein, 99g of carbohydrates, and 5g of fats per serving, it offers a more affordable option for those looking to build lean muscle without unnecessary fillers. The inclusion of healthy fats like MCTs and a superior carbohydrate blend featuring organic quinoa and oat fiber gives it an edge. While it lacks the digestive enzymes or HMB seen in more premium gainers like GNC AMP Mass XXX, its clean profile, use of quality ingredients, and lower price point make it ideal for athletes on a budget who still want a high-quality product.
