BSN® has developed a lean mass gainer for individuals looking for caloric support, which is necessary to maximize lean muscle recovery. Additionally, it can provide the level of nutrients required by an individual with a higher metabolic rate or an extremely intense training regimen that burns countless calories.

Complementing the multi-functional protein matrix within TRUE-MASS® is a blend of complex carbohydrates, providing useable energy for one's ever-active muscles. To maximize energy and recovery, MCTs and essential fatty acids lend a hand, in addition to BCAAs for promoting positive nitrogen balance, and glutamine peptides for maximal anti-catabolic effects.*
