PBAAs can enhance nitrogen retention up to 2X as much as regular food protein.* The more nitrogen your muscles retain, the bigger, fuller and stronger they can become.* - Mass will help you leap past other bodybuilders with muscular gains that take your physique from “decent” to head-turning impressive. Mass Aminos act as a trigger to force more gains from your food. This amino supplement stimulates energy metabolism and enhanced protein synthesis during training. Take Mass tabs every half hour throughout the day to keep your body in a positive nitrogen balance.* - Perfect for the 40+, hard gainers, natural physique athletes and anyone else committed to doing whatever it takes to make their muscles bigger, fuller, harder and stronger, naturally. - Reduces loss of muscle mass and strength during layoffs from training, and helps you “regain” muscle faster afterwards. Mass gives you a higher workout energy level, a better pump and greater mental alertness. Feed your muscles while you train. Take 12-24 Mass Tabs while you train. 2-4 every 10 minutes or so. * - Quality and Integrity matter… that’s why Beverly International is obsessed with using only the highest quality, research-based ingredients available.
