Optimized: Gold Standard 100% Isolate

Experience the Pinnacle of Protein Purity.

Optimum Nutrition Gold Standard 100% Isolate is crafted for those who refuse to settle. By using only the highest quality whey protein that undergoes a series of sophisticated filtration processes, "excess" is stripped away. The result? An ultra-pure, fast-digesting protein with 25g of Whey Protein Isolate per serving and less than 1g of fat and carbs.

The Gold Standard Advantage

• Pure Whey Isolate: 25g of high-quality protein per serve, filtered for maximum purity.

• Rapid Absorption: Fast-digesting formula designed to deliver amino acids to muscles when they need it most.

• Ultra-Clean Profile: Zero hidden fillers, ultra-low carbs, and less than 1g of sugar—ideal for lean muscle goals.

• Unrivaled Mixability: Formulated to dissolve instantly in water or milk with no clumping or chalky texture.

• Banned Substance Tested: Informed-Choice certified, providing peace of mind for competitive athletes and daily trainers alike.

How to Use

• The Perfect Shake: Mix 1 scoop with 200–300ml of cold water or your preferred milk.

• When to Take: Consume within 30–60 minutes post-workout to support recovery, or use anytime during the day to hit your daily protein targets.

• Sprint Fit Tip: Because this is an isolate, it’s incredibly thin and clean. Try it in your morning oats or a fruit smoothie for a high-protein boost without the heavy "milky" texture of standard whey.
