Musashi Bulk Protein is an ultra-potent, high-calorie mass gainer engineered for hardgainers, strength athletes, and active Kiwis striving to pack on serious muscle size and weight.

Key Benefits & Features

• High-Protein Mass Formula: Delivers a heavy-duty protein hit per serving to support muscle protein synthesis and repair damaged muscle tissue.

• Energy-Dense Carbohydrate Complex: Packed with fast- and sustained-release carbohydrates to replenish glycogen stores and fuel demanding workouts.

• Supports Caloric Surplus: Provides a convenient, high-calorie solution for hardgainers who struggle to hit daily mass-building calorie targets through food alone.

• Fortified with Essential Vitamins & Minerals: Enriched with micronutrients to support efficient energy metabolism, combat fatigue, and promote overall performance.

• Rich & Indulgent Shake: Blends smoothly into a delicious, creamy shake that makes boosting daily calories effortless and enjoyable.

How It Works

Achieving a larger frame requires consistent calorie abundance paired with progressive resistance training. Musashi Bulk Protein simplifies this process by delivering a multi-stage protein and carbohydrate matrix in an easily digestible format.

The bioavailable protein blend floods damaged muscle fibres with essential amino acids immediately post-workout to halt catabolism and trigger repair. Simultaneously, the robust carbohydrate profile drives an anabolic insulin response, transporting key nutrients directly into muscle cells while fully restoring depleted glycogen reserves. This dual macronutrient action optimizes post-training recovery, helping you overcome size plateaus and achieve lasting muscle growth.

Recommended Use

Mix 60g (approx. 1 ¼ level scoops) with 300ml of full-cream milk or cold water in a shaker bottle, or blend 120g (approx. 2 ½ level scoops) with 500ml of liquid for a maximum gainer dose. Shake or blend for 30 seconds until completely dissolved. Consume 1–2 servings daily, ideally within 30 to 60 minutes post-workout or between main meals to meet your daily mass-building goals.
