Stop forcing down bloated, heavy shakes that leave you exhausted before your workout even begins. Athletech Purest Mass Gainer is built for hardgainers, athletes, and lifters who want clean, calculated surplus nutrition without the sluggish digestion of old-school weight gainers. Packing 453 clean calories, 25g of multi-source protein, and a full 5g clinical dose of creatine into a manageable 124g serve, this formula delivers high-impact muscle-building fuel you can easily stick with every single day.

Key Benefits & Features

• Manageable Serving Size: Delivers 453 nutrient-dense calories in an easy-drinking 124g serve, eliminating heavy digestive discomfort.

• Multi-Stage Carbohydrate Matrix: Features 45g of clean maltodextrin paired with 19.1g of premium SusCarb® (Highly Branched Cyclic Dextrin) for sustained glycogen replenishment.

• Full Clinical Creatine Dose: Contains 5,000mg of Pürest Creatine™ per serve to accelerate strength gains and muscle cell volumisation without needing a separate supplement.

• Comprehensive 8-Source Protein Blend: Combines dairy isolates and concentrates with plant proteins to deliver 25g of complete protein and over 12.7g of total EAAs.

• Digestive Health Support: Fortified with 1 billion CFU of Bacillus coagulans probiotics to optimise nutrient absorption and support gut comfort.

How It Works

Traditional gainers artificially inflate their calorie counts by requiring massive, unpalatable servings that sit heavy in your stomach. Athletech Purest Mass Gainer approaches muscle growth with nutritional transparency. The carbohydrate profile pairs fast-acting maltodextrin with 19.1g of patented SusCarb® cyclic dextrin, ensuring rapid gastric emptying and consistent muscular endurance without sharp blood sugar crashes.

To power complete muscle recovery, the formula provides a sustained-release protein complex made from whey concentrates, whey isolates, whole milk, buttermilk, and clean plant proteins from pea, pumpkin, and sunflower seeds. This matrix is reinforced with 2g of added free-form Essential Amino Acids (EAAs) and a full 5g dose of micronised creatine monohydrate to maximise cellular energy (ATP) production, while shelf-stable probiotics ensure your digestive system handles every calorie smoothly.

Recommended Use

Mix 2 level scoops (124g) with 400–500ml of cold water or milk in a shaker bottle. Shake vigorously for 30 seconds and consume immediately. Take one serving daily post-workout or between meals to meet your daily caloric targets.

Beginner Tip: If you are new to mass gainers, begin with a half serve (1 scoop / 62g in 250ml of liquid) once daily and gradually increase to a full serving as your body adapts.
