Rule 1 Clean Gainer is a premium, high-density lean mass gainer engineered for hardgainers, dedicated lifters, and active Kiwis looking to pack on quality size without adding unwanted body fat. Delivering 560 full-spectrum calories per serving, this clean formula pairs 30g of fast, medium, and slow-digesting proteins with a complex carbohydrate blend derived from whole food sources. Free from inferior sugars, fillers, and unnecessary creamers, Rule 1 Clean Gainer provides the clean fuel your body needs to power heavy training, accelerate recovery, and achieve real muscle growth.

Key Benefits & Features

• High-Quality Caloric Density: Provides 560 clean calories per serving to support positive energy balance and lean weight gain.

• 30g Multi-Source Protein Blend: Combines Whey Isolate, Whey Concentrate, Hydrolysed Whey, and Micellar Casein for sustained muscle recovery.

• Whole Food Complex Carbs: Powered by organic quinoa, blueberry powder, sweet potato, and maltodextrin for steady energy without massive insulin spikes.

• Minimal Added Sugars: Formulated without unnecessary sugar, creamers, or soy protein to promote quality muscle gain over fat storage.

• Rich in Essential BCAAs: Naturally loaded with essential amino acids to stimulate muscle protein synthesis and reduce muscle breakdown.

How It Works

Building quality mass requires consuming more calories than your body burns, but the source of those calories determines whether you build lean muscle or gain fat. Rule 1 Clean Gainer solves this by utilizing a targeted 3:1 carbohydrate-to-protein ratio derived from high-grade nutrients. The multi-stage protein complex supplies an immediate spike in blood amino acid levels via whey isolates, while the micellar casein sustains tissue repair over several hours.

Simultaneously, the complex carbohydrate blend replenishes depleted glycogen stores following intense workouts without causing rapid blood glucose crashes. Added lipid fats from lipid-rich oils provide sustained metabolic energy and support cellular integrity. This nutrient-dense matrix delivers anabolic support that keeps your muscles fed, hydrated, and growing cleanly.

Recommended Use

Mix 2 full scoops (approx. 142g) with 400–500ml of cold water, whole milk, or your favourite plant-based milk in a Sprint Fit shaker. Consume immediately post-workout to kickstart recovery and replenish glycogen. On non-training days, consume one serving between main meals or prior to sleep to hit daily calorie and macronutrient targets.
