Optimum Nutrition Gold Standard Casein Protein Powder Chocolate Supreme 2LB

Amazon reviewers say this casein protein is praised for its taste, value, and protein quality, with many calling Chocolate Supreme one of the best-tasting caseins available. They also mention it works well for slow-release protein before bed and for overnight muscle recovery, though some dislike the thickness and have mixed opinions on mixability.

On iHerb and the Vitamin Shoppe, customers similarly describe the flavor as good and the texture as generally smooth, while a few note an artificial taste or a viscous consistency. Garage Gym Reviews says users and staff like the Chocolate Supreme flavor, describing it as very close to chocolate pudding.

On Reddit and other forums, the broader consensus around this product family is that it is dependable, filling, and effective for nighttime use, but not always the easiest to mix.

YouTube reviewers generally focus on the flavor, slow-digesting nature, and bedtime recovery benefits. A few videos are strongly positive, while one older review is notably negative about taste.
