GNC changed the flavor of the Vanilla - it's horrible now

I loved this product and have been using it for years - until they changed the flavor and now it's nearly undrinkable. It used to mix well with water and now it's weak and tastes like plastic. I cannot figure out why they ruined a perfectly good product. It's also in a different color container and I notice you need more of the product in each serving. The protein etc is unchanged so I have no idea why they did this other than probably to cut costs at the expense of their customers. Yuck! Time to shop for a substitute.

DELICIOUS, PERFECT, AND EASY ON THE GUT

Lets just say combining low calorie, zero carbs, with a delicious and creamy protein is where it's at. I usually mix it with a banana, peanut butter, amd some chia seed and let me tell you, you would want to make another one just for the taste lol. One of the best I've had in a long time and haven't used any other protein in the past 90 days. Give it a shot. Low calorie, BCAA, and great vitamins and minerals.

Delicious and I love that it's zero carb. I would not be able to hit my protein goals without it.

Unflavored whey protein powder

It's just my preference. I bought the unflavored as it does not have the artificial sweetener that the others have.

JANET MVerified Buyer

Moorning Smoothie

Every morning I make a Smoothie with 1 cup milk, 1 scoop Whey, 2 tablespoons of Greek yogurt, 1 teaspoon Vanilla Extract (takes the bite out of the Yogurt). YUMMY!! Starts my day just right.

Linda OVerified Buyer

Delightful banana

This is my new go-to for protein powder when I just want a plain shake (not a smoothie). The banana flavor is there but not so overwhelming or in-your-face. Not overly sweet, just a nice subtle banana flavor. I mix with water and it mixes well and isn't chalky or gritty

Jennifer MVerified Buyer

Highly recommend buying this product! It's the best!

Great shake! Great Flavor! I would recommend this to friends and family.:):)
