Review: Great taste - Great tasting product, and mixes well. This product has played a key role in the weight gain for our 15 yo son.
Review: It Works - Getting these extra calories, protein & carbs is really helping. I don't eat breakfast at all & hardly any lunch so I'll drink 1 scoop mixed with 2% milk in place of those meals (2 scoops/1 serving per day). I'm on my 6th container having 1 serving per day & went from 179-181 lbs to 188-191 lbs (6'00") in less than a month and a half. The chocolate peanut butter is by far the best flavor, especially if you add a Tbsp of peanut butter to it. It's also definitely helping with building muscle combined with lifting. Surprisingly fast results, great taste, a little high on the sugar, but great product.
