Masters class Olympic lifter
I've always been very careful about ingesting any supplements. I've lifted both power and olympic for most of my life (since 1966). I was having difficulty recovering from workouts and my muscles were sore a lot on my off-days. My coach recommended Casein. I started taking a scoop before bed at night. The vanilla tastes pretty good. I immediately noticed an improvement in my workouts and I wasn't sore in the mornings. I would recommend this as a recovery supplement.

It doesn’t mix real well without a blender. But it tastes good and is good if you use a blender.

Mixes great, I'll just choose a different flavor next time!
I love how easy it is to mix this stuff up! You can mix it with a spoon in a glass and it's not clumpy! However, the flavor I got, cookie dough, was a bit to sweet for me so I have to add less to a glass. So FYI if you guys don't like the sweeter stuff avoid cookie dough. Happy with the price of the product too!

All well, except customs delay
Product came as described. Price was good. The product did get stopped at customs in China, but an agent called me and requested the additional details they needed to get approved. Took an extra week to clear and arrive at my residence, but came in the end. Overall good experience and successful delivery. Better understanding of collecting appropriate China Customs details on order would probably help with more seamless delivery.

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
BEST ANSWER: Yes! Take it back & exchange it for one that is sealed down proper.
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.
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.
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).
