Taste and not watery.
Having gone through countless brands over the past 25+ years this brand has done the best in flavor and texture. Some brands are watery and some thick but this one is just right in both flavor and thickness. Mixes easy with cold water, other top brands I have to mix it with unsweetened chocolate almond milk to get the flavor drinkable. Have used OptimumNutrition for years but their flavors are a hit or miss and to thin for my liking. The Reeses flavor is not spot on but still has a peanut butter taste. First few days I drank it it tasted so good it made me want overindulge and make another one. Look forward to Cellucor expanding the flavors, My favorite is cookies and cream, Hint Hint..

Taste Amazing, even with just water
I had a buddy get this and I tried it. It tastes just like Reese's. Bought my own and have come back for another 5lbs. I mix with cold water and it's still fantastic. Highly recommend

Uesd to be so much better
I've used their products since 2020.When they reformulated the protein power ,the taste went down hill. It also used to be Isolate. The Heresy's mix is just off for me. The Ressese is just too sweet and oddly flavored .aswell.

great flavor
tast is great, i just not a fan of how thin it mixes. I cut the liquid down to 4 ounces but still blends too thin for me. the other protein i had from cellucor was COR PERFORMANCE i believe and it mixed thick like a shake. really good.
