I take this product every night before I go to bed. I love the taste and it goes down smooth and does not clump up like other products I've tried. I find that it the morning after taking this supplement I wake up not starving and feeling great. It has helped me, along with other supplements I take improve my physique and I've been able to cut down my body fat and gain muscle with this product. I look forward to anytime it is on sale on bodybuilding.com or featured with a gift. I recommend this protein as well as the ON whey protein to anyone. It is the best quality and taste of all protein supplements I've tried and it works great.

Great taste. I love the optimum line of products. My only caution to people is the fact that it is a casein protein. It is slow digesting so when you wake up in the morning after taking casein you never get that empty/ leaned out feeling. I personally think whey is a better choice but this product is a solid casein protein if you are feeling like you need casein.

I have been recently supplementing with casein. This is by far some of the best tasting protein power I've had. I absolutely love it. It mixes well, but I prefer it mixed with avocado and milk and making a paste like substance. This has beneficial to me as I am vegetarian. I would suggest this tasty protein.

It's a great product coming from a good company . If you take a look at the 1st ingrident it has Micellar Casein . You get 9grams of essential amino acids 24 grams of protein. I like to take this right before bed & why is that cause it's known as a slow digesting protein so it's feeding my muscles slowly while im sleeping .

Directions For Gold Standard 100% Casein:

Using a shaker cup is the easiest and most convenient way to mix up a consistently great casein shake every time. Just add one heaping scoop of Gold Standard 100% Casein™ to a shaker cup filled with 10-12 oz of your preferred beverage. Cover and shake for 25-30 seconds. TIP: Adjust the intensity of your Gold Standard 100% Casein™ by varying the amount of liquid that you use to prepare it. For a bolder flavor with slightly more body and sweetness, mix one heaping scoop with 8-10 oz of water, milk, or your favorite beverage. For a milder tasting, less sweet shake, use 12-14 oz of liquid per scoop.

PACKETS: Add one Packet of Gold Standard 100% Casein™ to a blender filled with 10-12 oz. of water, milk, or your favorite beverage. Blend for 20-30 seconds. Then add 3-4 ice cubes and blend for an additional 30 seconds.

BLENDER: Add one heaping scoop of Gold Standard 100% Casein™ to a blender filled with 10-12 oz of water, milk, or your favorite beverage. Blend for 20-30 seconds. Then add 3-4 ice cubes and blend for an additional 30 seconds.
SHAKE UP YOUR SHAKE: By adding a few high-energy ingredients to your shake you can blend up a delicious meal: try adding fresh or frozen fruits (strawberries, bananas, peaches, etc.), peanut butter, flaxseed oil, yogurt, coconut, slivered almonds, or other ingredients.
STACK YOUR SHAKE: By adding supplements like Micronized Creatine, Glutamine, Taurine, and/or INSTANTIZED BCAA powders, you can make Gold Standard 100% Casein™ an even more powerful recovery product.

SPOON STIRRED: If you forgot your shaker cup or don't have time to get out the blender, you can just add one heaping scoop of Gold Standard 100% Casein™ to a glass filled with 10-12 oz of cold water, milk, or your favorite beverage. Then mix it up with a spoon for about 30 seconds or until powder is dissolved.

SUGGESTED USE: Consume approximately 1 gram of protein per pound of body weight per day through a combination of high protein foods and supplements. For best results, consume your daily protein allotment over several small meals spread evenly throughout the day. TIP: Try using "slower" Gold Standard 100% Casein™ with "faster" proteins like Gold Standard 100% Whey™ or Pro Complex® at different times for maximum effectiveness. Take Gold Standard 100% Casein™ immediately before bed and in between meals when delayed protein delivery is desired. Drink Gold Standard 100% Whey™ or Pro Complex® proteins before and immediately after workouts for a rapid "shot" of amino acids.

Warnings: DO NOT USE AS A SOLE SOURCE OF NUTRITION FOR WEIGHT LOSS OR MAINTENANCE. KEEP OUT OF REACH OF CHILDREN.
