Formula changed and strawberry flavor has decreased
This protein powder used to have such a strong strawberry flavor, now it's just meh! I had an add powdered freeze dried strawberries to my powder to create a better flavor. Not very cost effective either. Wouldn't buy again.

Don't try strawberry.
I'm usually not picky about protein powder but the strawberry is the worst one I've ever tried. Weirdly almost flavorless but then it hits you with that chalky fake aftertaste. Super disappointed.

The best I’ve had in years
This strawberry flavor was absolutely delicious! I’m so excited to have found this brand after having ON and Isopure for years. I’ve definitely been missing out and can’t wait to try the other flavors. No chalky or aftertaste. It also tasted clean and very flavorful if that makes sense. I mixed with unsweetened almond milk and some water.
