Rule 1 Essential Amino 9 is a high-performance intra-workout and recovery formula engineered to support lean muscle preservation, accelerate repair, and maintain optimal hydration during intense training. Delivering a robust 7.5g of Essential Amino Acids (EAAs)—including 5g of Branched-Chain Amino Acids (BCAAs)—alongside an added electrolyte matrix, this zero-sugar powder fuels your muscles when they need it most. Formulated for dedicated lifters, endurance athletes, and active Kiwis who demand complete protein synthesis support, Rule 1 Essential Amino 9 keeps your performance elevated from the first rep to the last.

Key Benefits & Features

• 7.5g Full-Spectrum EAAs: Provides all 9 essential amino acids that your body cannot produce naturally, maximizing muscle protein synthesis.

• 5g Pure 2:1:1 BCAAs: Loaded with Leucine, Isoleucine, and Valine to prevent intra-workout muscle breakdown and reduce muscle soreness.

• Essential Electrolyte Blend: Packed with vital minerals to support hydration, maintain intracellular fluid balance, and prevent muscle cramping.

• Zero Sugar & Zero Gluten: Refreshing, light flavour profile crafted without added sugars, artificial stimulants, or unnecessary fillers.

• Transparent & Clean Formula: Fully disclosed amino acid profile with zero proprietary blends, artificial colours, or banned substances.

How It Works

While BCAAs are vital for initiating recovery, your body requires all nine essential amino acids to build and repair muscle tissue effectively. Rule 1 Essential Amino 9 supplies a rapid surge of free-form EAAs directly into the bloodstream during or after exercise. L-Leucine acts as the primary molecular trigger for the mTOR pathway, while the remaining eight EAAs provide the necessary building blocks to complete the process of muscle tissue synthesis.

Simultaneously, the integrated electrolyte matrix replenishes vital minerals lost through sweat during hard sessions. This maintains optimal hydration, cellular firing, and endurance while preventing metabolic fatigue and muscle cramping. By keeping your muscles hydrated and continuously supplied with building blocks, Rule 1 Essential Amino 9 prevents catabolism and speeds up post-workout recovery.

Recommended Use

Mix 1 level scoop (approx. 11.5g) with 300–450ml of ice-cold water in your Sprint Fit shaker. Consume during your workout as an intra-workout refresher, or sip throughout the day on non-training days to support continuous hydration and amino acid coverage.
