Excellent tasting protein!

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.

Great quality

Great supplement. I have been using this for more than 15 years and its stll have been the great supplement for me in terms of taste and quality. I have tried several other supplements too but always switched back to Gold Standard.

Flavorful Cost-effective Protein Supplementation

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.

Ideal for ON whey fans

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.

Tasted good not worth the price.

Tasted good and I liked it but the price now is out of control. I bought it at 49.99 and now it’s over 70$ nope. Took it right out of my cart.

ON Gold Standard Whey - Expensive

I've been buying this for more than20 years because it's the best - BUT - the price is more than doubled what it used to be - not very affordable and I may have to stop using it.

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.

Really no refund

I don't understand how this product received five-star ratings. Maybe I received a bad batch, not willing to spend the money to find out again, Sam will not refund the purchase price. First protein shake I made, I could have thought maybe the banana had a bitter taste to it. The next one, it was only I milk, and the protein powder taste did not change.
