Musashi Bulk Extreme is an advanced, high-calorie gainer engineered specifically for hardgainers, bodybuilders, and active Kiwis who struggle to build serious muscle size and weight. Delivering a massive combination of quality protein, energy-dense carbohydrates, and essential vitamins, this heavy-duty mass gainer provides the extra calorie surplus your body needs to fuel demanding workouts and support maximal muscle growth.

Key Benefits & Features

• Massive High-Calorie Load: Formulated to help hardgainers hit an extreme caloric surplus required for real size and mass gains.

• 50g Multi-Source Protein Per Serving: Delivers a heavy-duty dose of protein to fuel muscle protein synthesis and accelerate post-training recovery.

• Carbohydrate Matrix for Energy & Bulk: Packed with fast- and medium-digesting carbs to replenish depleted glycogen stores and support heavy training loads.

• Fortified with Vitamins & Minerals: Enhanced with key micronutrients to assist with energy metabolism, nutrient absorption, and overall vitality.

• Smooth & Indulgent Shake: Mixes easily into a rich, high-energy milkshake ideal for post-workout fueling or between-meal calorie boosting.

How It Works

Building significant muscle mass requires consuming more energy than you burn daily—a task that can be difficult through solid whole food alone. Musashi Bulk Extreme solves this challenge by supplying a concentrated balance of macronutrients in an easily digestible liquid format.

The high-grade protein matrix rapidly supplies essential amino acids to damaged muscle tissue post-exercise to halt catabolism and initiate structural repair. Simultaneously, the robust carbohydrate blend drives insulin spikes to optimize nutrient delivery into muscle cells while fully replenishing energy stores. By providing a clean, convenient way to increase daily caloric intake, it helps overcome metabolic plateaus and supports rapid weight gain and lean muscle expansion.

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 calorie dose. Shake or blend for 30 seconds until completely dissolved. Consume 1–2 servings daily, ideally post-workout or between main meals to hit your daily weight gain targets.
