Key Benefits & Features

• 24g Premium Protein Per Serve: Packed with ultra-pure protein sources to support muscle repair, lean mass gains, and rapid recovery.

• Whey Protein Isolate Primary Source: Micro-filtered Whey Protein Isolate (WPI) leads the blend, keeping fats, carbs, and sugars to an absolute minimum.

• 5.5g Naturally Occurring BCAAs: Rich in Leucine, Isoleucine, and Valine to spark muscle protein synthesis and preserve hard-earned lean tissue.

• Instantised for Easy Mixing: Effortlessly stirs clean into water, milk, or smoothies with just a shaker or spoon—no clumping or mess.

• Banned Substance Tested: Informed-Choice certified, giving New Zealand athletes total confidence and peace of mind during competition.

How It Works

Optimum Nutrition Gold Standard 100% Whey combines three high-quality dairy protein sources: Whey Protein Isolate (WPI), Whey Protein Concentrate (WPC), and Hydrolysed Whey Peptides. WPI serves as the primary ingredient, undergoing advanced cross-flow microfiltration to isolate pure protein while filtering out unnecessary fats, cholesterol, and excess lactose.

This fast-digesting triad rapidly shuttles essential amino acids straight into starved muscle fibers when your body needs them most. Combined with over 4g of naturally occurring glutamine and glutamic acid per serving, it helps prevent muscle breakdown and reduces post-training fatigue so you can bounce back stronger for your next session.

Recommended Use

Mix 1 level scoop (approx. 29.4g to 30g) with 200–250ml of cold water, low-fat milk, or your preferred beverage in a shaker cup. Shake or stir vigorously for 20–30 seconds until fully smooth.

• Post-Workout: Consume within 30–60 minutes after exercise to maximize muscle recovery.

• Daily Protein Boost: Enjoy first thing in the morning or between main meals to hit your daily target macros.
