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.

This has a very good flavor. More so than the double rich chocolate. It dissolves very well in milk.

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.

The best whey product out on the market! Appreciate the price you have it for. Space saving over canisters on my shelf.

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

Well a couple months ago I would have given this 5 stars for the quality and price. But it seems the greed once again slips into Sams pricing. So because it is now the average price for protein elsewhere, it gets an average rating. The prices at Sams aren't even better than just going to Walmart now.

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.
