Crafted from grass-fed whey and free from added sugars or artificial ingredients, this Halal-certified formula is designed for serious athletes and hard gainers aiming to maximize their muscle-building potential. ## Description Reflex Nutrition’s Instant Mass Heavyweight protein powder is developed for hard gainers and athletes seeking a quality blend of proteins and complex carbohydrates. With over 1000 calories per shake, this bulking protein powder formula fuels your body with substantial quantities of macronutrients for building and maintaining muscle mass. Our protien blend combines four premium sources of whey protein with slow-releasing micellar casein, catering to both immediate and sustained amino acid delivery. The Whey Protein Concentrate is carefully processed to preserve its purity, while Hydrolysed Whey Protein is enzymatically treated for rapid absorption. Together with Native Whey, these form a full-spectrum protein assault that contributes effectively to muscle growth and recovery. Instant Mass Heavyweight bodybulding supplement is crafted with a multifaceted carbohydrate matrix. This intelligent carb blend sidesteps the pitfalls of simple sugars and syrups, opting instead for a sustained-release energy supply - It's the perfect partner for the long, intense workout sessions. Each serving of protein supplements is also power-packed with 18 added vitamins and minerals, amplifying the nutrition profile and supporting your body’s demands through all phases of training - whether you’re prepping, pushing through, or in post-workout recovery, Reflex's weight gain protein powder formula will help you achieve your goals. Incorporated into this mix is creatine powder, scientifically proven to increase physical performance in successive bursts of short-term, high-intensity exercise, ideal for those aiming to dominate in their sport. This high protein shake is available in two sizes to accommodate your training intensity and frequency (protein powder 2kg and protein powder 5.4kg). Choose your flavour from a variety including traditional favourites and exciting new taste profiles (vanilla protein powder, strawberry protein powder, chocolate protein powder and more).
