Gold Standard 100% Isolate Whey Protein by Optimum Nutrition

Optimum Nutrition Gold Standard 100% Isolate is a premium whey protein isolate (WPI) supplement designed for maximum protein purity, fast digestion, and minimal carbs/fats.

• Uses ultra-filtered whey protein isolate + hydrolysed isolate
• Delivers ~25g protein per serving
• Very low in fat (<1g) and carbs (~1g)

This is essentially the “cleaner, leaner” version of their classic Gold Standard Whey.

2. Muscle Protein Synthesis

• Provides essential amino acids + BCAAs (~5.5g)
• Stimulates muscle repair and growth post-training

3. Lean Nutrition Profile

• Minimal lactose, fat, and carbs → ideal for cutting or lean muscle gain
