I have tried many brands of protein. This brand is excellent! I purchased both flavors vanilla and chocolate. Both have a great taste and I will definitely purchase again. I also use GNC for buying most of my protein supplements. The price is actually better than when GNC is have a sale.

Gold Standard Whey protein tastes pretty good and easily mixes in a blender with milk, coffee and/or water. At less than a dollar per serving, this supplementation solution is very cost-effective over buying the small 11-12 ounce servings, and it only takes about 30 seconds to blend. Recommended.

Optimum Nutrition's Gold Standard 100% Whey has been my go-to protein powder for years, and it continues to deliver both in quality and taste. The blend of whey isolate and concentrate provides an excellent protein source that's easy on the stomach and mixes smoothly — no clumping, even when using just a shaker bottle. Flavor-wise, it's one of the most consistent products out there. The Double Rich Chocolate and Vanilla Ice Cream flavors are both rich without being overly sweet, and they mix well into oatmeal, smoothies, or just water. Each serving gives you about 24 grams of protein, 1 gram of sugar, and minimal fat — perfect for supporting recovery and maintaining lean muscle without unnecessary fillers. It also digests well thanks to the added digestive enzymes (lactase), which makes it a good choice even for those sensitive to dairy. I've noticed faster recovery and less soreness after workouts when using it consistently post-training.

I've been hoping Sam's would carry Optimum Nutrition, and was delighted to find the Extreme Chocolate in the store by chance. The resealable bag is very convenient, and it's a great price.

It's really great to see tgis available in Sam's and at a great price. Even if it wasn't i would pay for conveniences having ot available. Overall a great product and i would recommend 👌🏼

I don't know how many gallons of this stuff I've chugged over the years, but the extreme milk chocolate is the best tasting protein powder I've found.

Great stuff why did you stop selling the members mark whey in a 5lb container for 37 bucks? Gold standard price sky rocketed and may need to buy else where

price went up $15 and Im not happy about that otherwise it be 5 stars

I usually love ON products, but not this one. When mixed up this protein powder is very thin and not very chocolatey. It is an isolate protein which had i known that I wouldn't have purchased it to begin with. It is marked isolate in small print on the bottom right of yhe yhe bag.

I mixed up my usual amount and took one sip only to find it was sour! Nothing worse than sour milk protein. I've had this issue more frequently with this brand. I will be returning this bag.
