True Mass 1200 4.8 Kg by BSN is designed for athletes with high caloric needs or difficulties in gaining muscle mass. This technical "gainer" uses a 4:1 ratio of complex carbohydrates to proteins, providing a dense energy substrate, ideal for glycogen resynthesis and supporting muscle anabolism after intense workouts. The multi-phase carbohydrate matrix, including whole grain oats, ensures steady energy release, avoiding insulin spikes and supporting controlled weight gain. With over 1200 calories per serving, its sustained-release protein blend ensures a constant flow of essential amino acids.
