Review: Great product! ON Casein FTW! - If you're serious about bodybuilding, or at least about gaining muscle and being a regular at the gym, chances are that you've done your research on protein supplements. Whey protein is fast releasing/absorbing. If you are looking for a supplement before bed/meal replacement once in a while, casein might be the way to go. I've been buying this product for about 1.5 years now and I'm totally satisfied with it. Let me break it down a little bit. - It tastes GREAT! Almost like a smoothie. - It mixes well with water, milk, coconut water (lol). - Peanut Butter - Bread sandwich with a Casein shake - Oh lord, it tastes heavenly. - I take Whey protein as well, so I can't really quantify the effectiveness of casein separately, but I can tell you have I have gained considerable muscle overall and have been able to build some strength as well. - Post workout recovery has been quicker, in my opinion, since this is extra protein intake. - It's *slightly* more grainy than ON 100% Whey, but that's okay! I think it's reasonably priced. I'm a huge fan of optimum nutrition and I am a vegetarian. I can use all the protein I can get and I totally don't mind buying casein in addition to 100% Whey. PS: Casein + Plain oats taste great! I used to have oatmeal with Whey but thrown in Casein shake with regular oats, it tastes SO MUCH better, I actually enjoy having oatmeal.
Review: Great before bed - I drink this before bed to help with recovery and that extra bit of protein. It taste great and I feel it helps me sleep faster/better. To get it to 100% dissolve, I use room temp water to mix it then refrigerate a few hours before bed. You're left with a creamy and clump-free drink!

### ⭐⭐⭐⭐⭐ Great product! ON Casein FTW!

### ⭐⭐⭐⭐⭐ Great before bed

### ⭐⭐⭐⭐⭐ Peanut Butter flavor gave me faith in this Casein again!
*by L***N on December 14, 2019*

I had previously tried the cookies and cream casein and it was very subpar. Then I decided to try peanut butter. Delicious! I gave it another try because the casein works really well. I wake up much less sore and it has great macros. It mixes well, but in my experience it will start to stick to the edges of my cup when I leave it in the fridge for a few hours. Not really a deal breaker. Just something to note. I usually like my protein with milk, but this honestly tastes better with water. The flavor doesn’t need any support because it’s already good on its own.
