Description

To create Gold Standard 100% Isolate, we start by selecting only the highest quality whey protein which undergoes a series of sophisticated filtration processes to ‘isolate’ out excess fat, cholesterol and sugar. A portion of this Whey Protein Isolate is then hydrolyzed – broken down into smaller chains of amino acids. The final product is a fast digesting complete protein containing no more than 1 gram of carbohydrates, less than a gram of fat and more than 80% pure protein per Serving.

    • Great Protein Powder. Body loves it and my stomach loves it even more
Flavor Name: Chocolate Bliss Size: 3 Pound (Pack of 1)
I have always loved OP protein supplements and I recently switched to this isolate because the hydrolyzed version was getting too expensive with the inconsistent prices. Upon switching to this I was worried about my digestion but I honestly can't differentiate the difference which is a good thing. My stomachs happy and I am happy. The taste is good especially with milk but I usually just use water to save on the calorie count. Dissolves easily and does not clump. Still always recommend a shaker ball. I do believe it is an effective protein powder and very high quality. The calories and carbs are more than fair as well. ... show more

Flavor Name: Chocolate Bliss Size: 3 Pound (Pack of 1)
High-quality isolate – clean, effective, and great taste I’ve been using the Optimum Nutrition Gold Standard 100% Isolate for a few weeks now, and I’m thoroughly impressed. It mixes smoothly with just water, no clumps at all, and the flavor (I got the chocolate) is surprisingly good, not too sweet or artificial. It’s light on the stomach, easy to digest, and perfect post-workout. I also love that it’s low in sugar and carbs, with a high protein content per scoop. You can really tell it’s a clean, high-quality product. value : You got what you pay for! 💰 Definitely a go-to for anyone serious about their protein intake. Highly recommended! ... show more

    • Smooth, Great Taste & High-Quality Protein
Flavor Name: Chocolate Bliss Size: 3 Pound (Pack of 1)
This protein powder is excellent if you’re looking for something clean, fast-digesting, and easy on the stomach. The Chocolate Bliss flavor is rich without being overly sweet, and it mixes smoothly with water or milk—no clumps or chalky aftertaste.

    • Review not about the product but about buying experience
Flavor Name: Chocolate Bliss Size: 3 Pound (Pack of 1)
The product itself is great. Quality item and flavor IS not as artificial as other brands; I have been using ON for many years. My problem is that I GOT THE WRONG FLAVOR; IT SEEMS THAT AMAZON DISCONTINUE THE FLAVOR THAT I CHOSE AND THEN THEY SEND WHATEVER FLAVOR THEY HAVE. I'm not returning the item because I will lose the promotional code that I use, and still I will not get the original flavor that I want it. ... show more
