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.

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.
