I was surprised to see such a protein-focused product from a company like Gatorade, since even most of their efforts at branching out beyond carb-heavy products tend to be geared mostly toward endurance with little muscle gain focus. However, the Recovery series whey protein bar has 20 grams of protein (though not all from high-quality sources - the two main sources are whey protein concentrate and modified corn starch). Of course, to the rest of the mass-gaining world, 20 grams isn't that much, particularly for a bar that weighs in at 340 to 360 calories, depending on the flavor. As a result, this is not really going to be a great option for cutting, but perhaps it was intended as a bulking bar. If so, the people at Gatorade seem to be adhering to the doctrine of dirty bulking, as you'll get up to 31 grams of sugar per bar. Then again, Gatorade is straight sugar, so perhaps we should be thankful.
Interestingly, despite the fact that they have been embraced for their antioxidant qualities, the bar does not have any beta-carotene, vitamin E, or vitamin C. In fact, unlike many protein bars, this bar doesn't have much at all in the way of vitamins and minerals, so it is not a great overall health/comprehensive meal replacement bar either. While protein is promoted as the star of this bar, it also has 42 grams of carbohydrates and 12 grams of fat (including 9 grams of saturated fat). Those aren't really flexible macro breakdowns for a lot of people, but after a hard workout or sports it can be suitable.
Tastewise, the Chocolate Chip is your best option. It has a rich chocolate flavor that doesn't taste too much like protein bar cardboard or like chemicals. The Chocolate Caramel is a little to sweet and very dry, while the Cookies and Cream just misses the mark.
