Strawberry Cream flavor
Good strawberry flavor.
Not as hyper-sweet as some of the other flavors.

Seems to separate faster - often have to guzzle shake.
Tastes a little chalky (like the old Flintstones vitamins).

Would purchase again, but still looking for a favorite flavor.

Was a little worried about buying this product because of many reviews that it was chunky or gritty but it was not!!! I mixed it in my shaker for a little less than 30 secs and it tasted so good!! I would really buy this for the rest of my life

It tastes great! But this tub just mixes terribly... I don’t know why nobody else has this problem but it’s just so chunky for me.

Is this protein a good way to loose weight fast if not which one is? please answer hopping to get a better body
A shopper on Apr 14, 2013
BEST ANSWER: Casein protein in milk may aid weight loss due to its effect on appetite, calorie burning, and body composition.
Should I take this with Whey Protein?
A shopper on Jul 30, 2013
BEST ANSWER: Product description does not include consuming whey protein with item.
Do i take this with Whey protein too?
A shopper on Feb 15, 2010
BEST ANSWER: For best results yes, you should use casein and whey.

Whey protein is best for an immediate release like right after work outs.

Casein protein is time released and is better for a steady protein supply over longer periods, like taken right before bed.

Combined they'd give the best results.
I bought this and the white seal on the inside was inside the lid. Should it have been glued on?
A shopper on Apr 9, 2016

Can you take Casein protein with whey protein?
When is the best time of the day to take casein protein?
A shopper on Jan 10, 2010
BEST ANSWER: Yes, you most certainly can take Casein protein with whey protein. The best time to mix the two would be immediately after your workout. The best time of the day to take Casein protein is right before bed (because this is the longest time your body goes without food, and the slow-digesting proteins keep your body in an anabolic state for the majority of the night).
Is casino dairy free?
A shopper on Jun 5, 2018
BEST ANSWER: No, casein is actually the main protein found in milk.
i just want to know if drinking this protein is good to gain weight without exercising
A shopper on Dec 11, 2012
BEST ANSWER: Yes, consumption of Optimum Nutrition 100% Casein Protein - Cookies and Cream will cause weight gain. If exercise is not involved in the weight gain process the weight gained will not be muscle tissue, it will instead be fat tissue that can lead to cardiovascular disease.
If I take Whey protein before and after my workouts, can I still use this before bed?
A shopper on Jul 23, 2012
BEST ANSWER: For the simple fact that whey is a rather strong product I wouldn't recommend doing more than one dosage a day.
How old should I be to take protein shakes?
A shopper on Apr 8, 2012
BEST ANSWER: The label indicates that this particular product should only be consumed by persons over the age of eighteen. There may be other protein shakes on the market that have no such age restrictions. Muscle Milk, for example, has no age limit.
