Verified Purchase

most big tubs usually takes inane amount of scoops,with this,says 22 servings at 24g of protein per scoop, i use 2 for 48... if training this is alot more convenient. i also advise to get 2... realistically gym goers etc probably would need 2... im surprised other than the low cal. i like it.

Perfect Strawberry

This is a very good strawberry flavor. It's not too sweet for me, but still has a very prevalent strawberry taste. As usual with ON products, it's very thin and doesn't have too much taste with water, but it's still easy to get down. With just a little bit of added fat with almond milk, it's perfect.
