Good Casein - Reasonable Price
Quality casein powder for those who want to avoid the whey. Flavor is solid and mixes well. Like all manufacturers, the bottle is half air (weight is fine, but I despise the packaging).

Perfection!
First off, the Chocolate Supreme taste is amazing. I mix 1 scoop with 12 ounces of 2% milk, and it tastes like a chocolate milkshake. Mixed with milk, the taste is a solid 5/5. However, I've also mixed it with water before and without the milk the taste score lessons to about a 3/5. If you are planning on buying this product, I would intend on drinking it with milk. That may be a problem for someone with lactose intolerance, or someone that just plain doesn't like milk, and I'd recommend finding a different flavor that mixes well with water in that case. Do not let that dissuade you though, this product has many more benefits then just taste. Casein is a slow digestive protein so consuming it will keep you full for several hours. I personally like to take it before bed so that it keeps me full while I sleep. This prevents waking during the night from hunger, and feeling starved in the morning from not eating for 6+ hours. It's also good to take before going out somewhere if you aren't going to be eating for a number of hours. Also, as a Type-1 diabetic, I've noticed that since I've been taking this supplement I haven't had any low blood sugars upon waking up in the morning. Anyone with diabetes can tell you that a low blood sugar level can be a serious issue, but since I've been taking casein before bed I find that my blood sugar levels are always at a healthy level when I wake up. I'm not 100% sure how it works, but I assume the slow digestion of the protein is to thank. The last point I'd like to make is about the potential as a supplement for helping build muscle. As far as protein supplements go this is easily the best I've ever taken. I started using this product in mid-August and since then I have put on 20 pounds of muscle. I realize there are other factors in play, such as, diet and exercise regimen, but I have used other protein supplements in the past, and I have never seen results as good as this before. Again, I believe taking casein at night, and keeping your body full as it rebuilds muscle is a contributing factor to the gains I've had. All in all, this is a fantastic product that I will continue to purchase time and time again. I reccommend to anyone that is looking for a great tasting protein supplement that will help you gain muscle. Also, to anyone that suffers from low morning blood sugar levels, this product really has completely stopped them for me. 5/5

Taste good, Price has always been excellent, Simple Protein, Meal Replacement
I use this as a meal replacement maybe 3 times a week and it really helps. The nutritional value and protein quality are both excellent for the price as far as im aware.The ingredients are simple and not packed with junk, which I appreciate. The seal is always tight and fresh when it arrives. It mixes easily with milk or water, tastes good enough for a protein. If I mix a banana, oatmeal, a scoop and a half, and sometimes whatever else I'm feeling - Blend for a little and you can use anything to mix it, it'll taste great.

Me encanta el sabor. Espesa bastante en bebida de almendras. Se disuelve mal, pero con batidora o espumador de leche queda perfecto.

Siempre la mejor calidad de Gold Standard, tambien con un buen sabor. Relacion Precio / Calidad, un poco alto el precio. Pero considerando todo, vale la pena. Solo Optimum Nutrition para mi proteina! Caseina con Avena no esta mal y este sabor de chocolate hace la avena un poco mas aguantable... ;)

日本製とは違うと覚悟はしていましたが、普通に飲むこともできないくらい味が濃かったです。 普通サイズのシェーカーでは到底薄めることはできなかったです。 高タンパクだったので、期待したかったのに後悔しか残りません。

I’m a huge fan of Optimum Nutrition whey, and this product did not disappoint either. The powder dissolves easily and mixes smoothly, with a chocolate flavor that tastes really good — definitely enjoyable to drink. One thing to keep in mind is that this casein requires more liquid per scoop compared to whey to achieve the desired consistency, but that’s typical for slow-digesting proteins. It works perfectly for overnight muscle recovery and helps keep you full longer. Overall, a high-quality casein protein that delivers on taste, mixability, and effectiveness. A reliable choice for anyone looking to support muscle recovery or stay satiated overnight.
