How It Works
Rule 1 R1 Protein Isolate operates by supplying your muscle tissue with rapidly absorbed, highly bioavailable peptide fractions immediately following physical exertion. By utilizing only cross-flow microfiltered whey isolate and hydrolysed whey isolate, the protein is pre-cleaved into smaller amino acid chains. This bypasses lengthy digestive delays and rapidly elevates blood amino acid levels when your body is most receptive to recovery.
The high concentration of naturally occurring Leucine and other Branched-Chain Amino Acids (BCAAs) directly triggers muscle protein synthesis, assisting in repairing micro-tears in muscle fibers caused by intense weightlifting or conditioning. Because unnecessary fats, sugars, and lactose are filtered out during production, R1 Protein Isolate provides an anabolic boost that supports lean body composition without triggering bloating or digestive distress.
Recommended Use
Mix 1 level scoop with 200–250ml of cold water or your favourite milk in a Sprint Fit shaker. Shake well for 15–20 seconds until fully blended. Consume immediately post-workout to kickstart recovery, or use first thing in the morning and between meals to meet your daily protein requirements.
Rule 1 R1 Isolate Protein Frequently Asked Questions
What type of protein sources are used in Rule 1 R1 Isolate?
Rule 1 R1 Isolate features a premium, ultra-filtered dual-source matrix composed entirely of Whey Protein Isolate (WPI) and Hydrolyzed Whey Isolate. Unlike standard protein blends, it contains absolutely no whey concentrate, creamers, or inferior dairy sub-products, creating a highly rapid digestion velocity that instantly supplies critical building blocks to muscle tissue post-workout.
What are the exact macronutrient and amino acid metrics per serving?
Each standard 29g to 31g level scoop (varying slightly by flavor selection) provides a highly concentrated, lean macronutrient breakdown engineered for strict fitness goals:
Protein: 25g of pure, ultra-purified isolate and hydrolyzed protein.
BCAAs: Over 6g of naturally occurring Branched-Chain Amino Acids (including an exceptional concentration of L-Leucine).
Glutamine: Contains over 4g of naturally occurring glutamic acid to support structural tissue recovery.
Macros: Only 100 to 110 calories, zero fat, zero sugar, and virtually zero carbohydrates per serving.
What is the functional difference between Rule 1 R1 Isolate and Rule 1 Whey Blend?
The core differences lie in structural purity, digestion speed, and calorie density:
Rule 1 R1 Isolate: Features 100% pure isolate and hydrolyzed protein with all creamers, sugars, and fats fully stripped out. It digests incredibly fast, contains only 100 calories, and is built for elite lean toning or post-workout cellular uptake.
Rule 1 Whey Blend: Incorporates standard Whey Protein Concentrate (WPC) alongside isolates. The inclusion of concentrate provides a slightly thicker, milkshake-style consistency and a more economical cost-per-serving option.
Does Rule 1 R1 Isolate contain lactose or gluten?
Rule 1 R1 Isolate is formulated to be 100% gluten-free. Because the advanced micro-filtration process strips away nearly all raw dairy sugars and fats, it contains virtually zero lactose. This highly purified structure makes it exceptionally well-tolerated by Kiwi fitness enthusiasts who experience stomach bloating or gas from standard concentrate blends.
Is this formula completely free from thickeners and creamers?
Yes. Rule 1 R1 Isolate uses an ultra-clean manufacturing philosophy. It contains zero lipid creamers, zero gums (such as xanthan or guar gum), and zero fill-agents. This ensures that you are paying purely for high-yield protein rather than cheap texturizers, resulting in a thin, light, and incredibly crisp drink consistency that mixes instantly without clumping.
How many servings are in the 1lb, 2lb, and 5lb container sizes?
Based on the standard level scoop, the exact serving volumes stocked at Sprint Fit include:
1LB Tub: Yields 14 to 16 full servings (perfect for assessing a brand-new flavor profile).
2LB Tub: Yields 30 to 32 full servings (a highly portable monthly training supply).
5LB Tub: Yields 76 full servings (delivering the absolute best long-term cost-per-scoop value for daily athletes).
