Optimum Nutrition Gold Standard 100% Whey is a reliable, well-priced everyday whey: 24 g of protein per 30.4 g scoop, wide flavour choice and good value in the 5 lb tub. It is not a pure isolate, so if dairy upsets you or you want the leanest possible shake, an isolate may suit you better. Here is what is in the tub, what it costs per serve in Australia, and who it suits.

FAQs
Is Optimum Nutrition Gold Standard whey good?
Yes. It gives 24 g of protein per scoop with 3 g of carbs and 1 g of fat in Double Rich Chocolate, it is banned substance tested under Informed Choice according to Optimum Nutrition, and the 5 lb tub works out at about $2.97 a serve. It is a whey blend with isolate as the main ingredient rather than a pure isolate.
How many serves are in Gold Standard Whey 5 lb?
The 2.27 kg (5 lb) tub of Double Rich Chocolate holds 74 serves of 30.4 g, and the 907 g (2 lb) tub holds 29 serves. Serve counts can vary slightly between flavours, so check your label.
Is Gold Standard Whey an isolate?
Not entirely. Whey protein isolate is the first ingredient, but it is blended with whey protein concentrate. If you want a pure isolate, look at Gold Standard 100% Isolate, Dymatize ISO100 or R1 Protein WPI.
What is the best Gold Standard Whey flavour?
Double Rich Chocolate is the classic choice, and Cookies & Cream and Vanilla Ice Cream are popular all-rounders. Taste is personal, so if you are unsure, start with a 2 lb tub before committing to 5 lb.
