Good lunch substitute
Mix with kefir, almond milk, and fresh strawberries. Have this for lunch at work. Put a small amount of liquid in shaker cup with whey powder. Shake then add remaining liquid and shake again. Mixes better with less liquid.

One of the best proteins I've used for price and quality.
The unflavored option is great for adding to things like oatmeal, pancakes, or milkshakes without adding any unwanted flavor. Mixes well with just water as well, no chunks.

Decent Protein
Taste is good (tried peanut butter and banana flavors). Mix-ability is about average compared to other brands. Overall considering price and typical deals when buying from GNC, this protein powder is a good deal.

Great Product
I have been using GNC 100% Whey for 2 years. This was my first time trying the vanilla. It is pretty good. However, the natural chocolate still is the best by far.

Amazing variety of taste
I 100% recommend this product, good gains and AMAZING flavor. If you want to know which flavor to get look towards the Banana Cream and Chocolate Supreme, those are my favorites! Honorable mentions are natural vanilla and cookies and cream. STAY AWAY FROM STRAWBERRY CREAM. Taste really unpleasant and like a "fake" strawberry shake. Other than that very good experience!

I thought the banana was delicious, then I tried the peanut butter. OMG. Does not taste like whey. Taste and low calorie content are shockingly good.
