Is Gold Standard 100% Whey an isolate (WPI)?

Not exactly. Gold Standard 100% Whey is a premium whey protein blend with whey protein isolate as its primary ingredient, supported by whey protein concentrate and whey peptides. This gives you the lean, fast-absorbing qualities of WPI in a more accessible everyday protein. If you're after a pure isolate, take a look at Optimum Nutrition Gold Standard 100% Isolate instead.

How do you use Gold Standard 100% Whey?

Add one scoop to 180 to 240ml of cold water or milk and stir, shake or blend until mixed. Have it within 30 to 60 minutes of training, or any time of day to help reach your protein target. Most people use one to two serves daily depending on their goals and how much protein they get from food.

How much protein is in Gold Standard 100% Whey?

Every serve provides 24g of protein, regardless of flavour. Exact fat, carbohydrate and kilojoule figures vary slightly between flavours, so check the nutrition panel for the flavour you choose.

Is Gold Standard 100% Whey gluten free?

Yes, Gold Standard 100% Whey is gluten free. It does contain milk and soy (soy lecithin), so it isn't suitable if you need to avoid dairy or soy.

Does Gold Standard 100% Whey contain creatine?

No, it doesn't contain creatine. If you'd like to add creatine to your routine, Optimum Nutrition Micronised Creatine stacks well alongside it.

What does Gold Standard 100% Whey stack well with?

• Creatine Supplements: the most evidence-backed pairing for building strength and size. It's taken daily, mixes straight into the same shake, and supports the muscle growth the protein is already working towards.
• Pre-Workout Supplements: taken around an hour before training for energy, focus and pumps, it covers the front end of your session while whey handles recovery afterwards.

For most people the foundation is whey plus daily creatine and possibly pre-workout depending on your specific goal.

From your first session to your thousandth, Gold Standard 100% Whey is a reliable, great-tasting protein to support training, recovery and your daily protein needs. Shop now at Nutrition Warehouse.
