Frequently Asked Questions
How much protein is in one scoop of Gold Standard 100% Whey?
Each serving (one rounded scoop) of Optimum Nutrition Gold Standard 100% Whey delivers 24g of protein and 5.5g of naturally occurring BCAAs. One 5lb tub provides about 68–74 servings depending on flavour — check the label on your container.
Is Gold Standard Whey a weight-loss product?
No. The tub says: "Use this product as a food supplement only. Do not use for weight reduction." What it does offer is 24g of protein per serving with little sugar or fat, so it fits easily into a diet where you are tracking calories and protein.
Does Optimum Nutrition Gold Standard Whey contain lactose?
Yes. Gold Standard 100% Whey contains whey protein concentrate, which naturally contains lactose, so it is not a lactose-free product. It contains milk and soy. If you are allergic to milk or soy, do not use it. If you are lactose intolerant, check the ingredient list on your container — Canadian and US labels can differ.
What is the difference between Gold Standard 100% Whey and Gold Standard 100% Isolate?
Gold Standard 100% Whey uses a blend of whey protein isolate (listed first), whey protein concentrate and hydrolyzed whey — 24g of protein at about 120–130 calories per serving depending on flavour. Gold Standard 100% Isolate uses whey protein isolate as its protein source, with slightly more protein per serving and fewer carbs and less fat. The Isolate may suit people tracking macros closely; for most regular gym-goers, the standard Gold Standard Whey is a solid everyday option.
Is the Gold Standard Whey at Bulldog Nutrition authentic?
Yes — Bulldog Nutrition is an authorized Canadian and US retailer of Optimum Nutrition, online since 2016. All stock comes through authorized supply channels and is 100% authentic, never grey market or counterfeit.
