Reflex Nutrition Instant Mass Heavyweight is a premium weight gain supplement expertly formulated for individuals serious about building muscle mass, increasing caloric intake, and supporting overall fitness goals. Designed to meet the needs of athletes, bodybuilders, and hard gainers, this advanced formula delivers a powerful blend of high-quality proteins, complex carbohydrates, and essential nutrients to fuel muscle growth and enhance recovery.

Each serving provides a comprehensive amino acid profile through a unique combination of whey protein concentrate, milk protein concentrate, and egg white protein, ensuring sustained release of amino acids necessary for optimal muscle repair and development. The carbohydrate matrix, derived from sources such as organic oats, barley, maltodextrin, and whole grain oats, supplies a steady release of energy to power intense workouts and maintain endurance throughout the day. Additionally, healthy fats including medium-chain triglycerides (MCTs) contribute to the supplement’s high caloric density, making it an ideal choice for those looking to increase their overall calorie consumption effectively.

Enriched with a broad spectrum of vitamins and minerals, including magnesium, zinc, and vitamin B6, this formula supports overall health, muscle function, and well-being during demanding training periods. The inclusion of creatine monohydrate further enhances strength and performance, helping you push your limits in the gym and accelerate your progress.

Reflex Nutrition prioritizes quality and purity, ensuring Instant Mass Heavyweight is free from artificial colours, flavours, and preservatives. Suitable for vegetarians, it caters to a wide range of dietary preferences without compromising on taste or nutritional value. Whether mixed with water or milk, the powder creates a smooth, creamy shake available in delicious flavours that make post-workout nutrition enjoyable and satisfying.

Ideal for those with high metabolic rates or anyone struggling to gain weight, this supplement delivers substantial calories per serving to support healthy mass gain and muscle development. Its convenient powder form allows for easy integration into your nutrition regimen, helping you elevate your training and achieve your physique goals with confidence.
