USN Hyperbolic Mass is an ultra-high-calorie all-in-one mass gainer designed specifically for "hardgainers"—individuals with fast metabolisms who struggle to pack on size and lean muscle mass. Unlike the pre-workouts and amino acids discussed earlier, Hyperbolic Mass is a dense meal replacement engineered to deliver a massive caloric surplus along with performance-boosting nutrients.
Because of its heavy carbohydrate and protein content, it is primarily used during intense bulk phases to accelerate muscle recovery and weight gain.
