Optimum Nutrition Gold Standard 100% 乳清蛋白粉，肉桂捲口味，1磅（1包）

Mixed this with almond milk for breakfast and it dissolves with almost no clumps—big win for busy mornings. The cinnamon roll flavor is spot-on, not overly sweet. Already ordered the bigger size.

Finally a cinnamon roll protein that doesn't taste like artificial cinnamon—mixes into oatmeal with no clumps. The scoop is decent for a small bag.

Mixes up really smooth in my shaker with no clumps, and two scoops actually keeps me full through my morning meetings. Taste is like a bakery treat without the guilt.
