Solid

As billed great supplement. Some tips when adding to coffee - mix separate in shaker with only 4-6oz lukewarm H2O. The mix becomes frothy and adds to coffee without clumping. Overall this has been an awesome addition to daily protein intake. Additionally, though I'm lactose intolerant no issues with my stomach. Already bought more

Excellent, clean protein powder. I use it in my oatmeal, plain non fat greek yogurt,and unsweetened almond milk and love it. The best protein powder on the market. I love the fact that it is also loaded with essential vitamins and minerals since I do not take any vitamins. Thank you Sam's club for carrying this product at such a good price. You definitely beat out GNC and The Vitamin Shop.

Clean

No taste. Goes well in my coffee every morning. Clean ingredients compared to most. Could blend a little better but a hand blender does the trick. Reason for 4 stars.
