Trust & Pharmacist Advice
Weight gain supplements are most effective when used alongside a structured resistance training programme and a balanced, calorie-controlled diet. Serious Mass is designed to supplement your daily nutrition rather than replace balanced meals.
Because each serving provides a substantial amount of calories and carbohydrates, many users find it easier to begin with half a serving and gradually increase intake as tolerated. Staying well hydrated is particularly important when using creatine-containing supplements.
