Lean all-in-one mass gainer for serious size, strength, and recovery.
Critical Mass Professional is a premium, fully loaded mass-building formula engineered for athletes who demand more from every training session. This high-calorie, macro-dense blend delivers precise amounts of protein, carbohydrates, creatine, amino acids, HMB, HICA, digestive enzymes, probiotics and metabolic support ingredients—everything required for rapid muscle growth, improved strength and optimised recovery.
