Rare amino-based nitrogen-retention technology: Mass Amino Acids (Mass) contains a rare casein hydrolysate rich in peptide-bonded amino acids (PBAAs).
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.
Perfect for the 40+ (40 years and over), 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 fat-loss or cutting diets and layoffs from training, and helps you “regain” muscle faster aftelrwards.
