Our take on the Optimum Nutrition Gold Standard 100% Whey Protein Powder Chocolate Peanut Butter

Gold Standard 100% Whey is Optimum Nutrition's flagship whey powder, built on whey protein isolate as the main source with hydrolyzed isolate added for faster absorption. Each scoop delivers 24 g of protein and 5.5 g of BCAAs, and it is one of the most widely used and widely reviewed whey powders on the market. It suits lifters who want a fast-digesting post-workout shake and a familiar, easy-mixing formula. Against isolate-only rivals it carries more lactose and a little more carbohydrate and fat per scoop, and its taste is sweeter than plain unflavored whey.

Questions and answers

How much protein is in one scoop?
One scoop provides 24 g of protein and 5.5 g of BCAAs. That fits a typical post-workout serving for most lifters.
Is this a whey isolate or a blend?
It is a blend led by whey protein isolate, with hydrolyzed isolate and whey concentrate also included. It is not a pure isolate.
Does it contain lactose?
Yes, because whey concentrate is part of the blend. People with lactose sensitivity may notice bloating; a pure isolate may suit them better.
How should I mix it?
Add one scoop to water or milk in a shaker cup and shake, or blend into a smoothie. It also stirs into oatmeal and yogurt.
How does it compare with a pure isolate powder?
It has slightly more carbs and fat and a creamier, sweeter taste. Pure isolates are leaner and lower in lactose but often plainer and thinner.
Is it suitable for beginners?
Yes. It is a straightforward everyday whey that works for beginners and experienced lifters alike, alongside strength training.
