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!

### ⭐⭐⭐⭐⭐ You get used to the flavor
*by M***D on February 20, 2022*

Honestly, I got this huge tub of casein for a STEAL when I purchased it. It’s not expired, had both seals, mixes well.. yano, all the bells and whistles! Going from the chocolate flavor to the chocolate peanut butter flavor is definitely a noticeable change. The chocolate is absolutely amazing but the chocolate peanut butter look a bit longer to get used to.. just has a somewhat tad off nutty flavor i guess you can say. I love the taste of it now though and am extremely happy with it especially for the price I was able to snag it for. Casein is casein at the end of the day.. I’m definitely not complaining.
