Reflex Nutrition Instant Mass® Heavyweight

Reflex Nutrition Instant Mass® Heavyweight is a premium mass gainer developed for hard gainers, strength athletes, bodybuilders, and anyone struggling to consume enough calories to support muscle growth and body weight goals. Every full serving delivers an impressive 1160 kcal, 60 g of premium protein, 203 g of carbohydrates, and 3 g of Creapure® Creatine Monohydrate, making it one of the most complete weight gain supplements available.

Unlike many traditional gainers, Instant Mass Heavyweight combines four premium protein sources including Whey Protein Concentrate, Micellar Casein, Native Whey Protein, and Hydrolysed Whey Protein. This multi-phase protein blend provides both rapidly and gradually digested proteins, helping to support muscle protein synthesis throughout the day and overnight.

The advanced carbohydrate blend supplies long-lasting energy for demanding training sessions, while the addition of Creapure® Creatine helps increase physical performance during repeated bursts of high-intensity exercise when consumed daily at 3 g. The formula is further enhanced with L-Glutamine, Glutamine Peptides, L-Choline Bitartrate, LactoSpore® Probiotics, BioPerine® Black Pepper Extract, and a comprehensive complex of vitamins and minerals to support daily nutrition and performance.

Whether your goal is increasing body weight, building lean muscle mass, or simply adding quality calories to your diet, Reflex Instant Mass Heavyweight provides an all-in-one solution trusted by athletes worldwide.
