QUALITY

After training, you want a fast-acting whey protein shake to kick-start the recovery process. But that process can take up to 48 hours to complete. Supplementing your healthy, balanced diet with slowly digesting Gold Standard 100% Casein™ can help support a feeling of fullness while providing a slow, steady flow of Essential Amino Acids including the BCAAs to muscle tissues. With nine different flavors to choose from, this is the standard all other slowly digesting proteins are measured against.

As one of the few companies to own and operate state-of-the-art manufacturing facilities that are GMP compliant, ON assures that every shake will mix up effortlessly because of its first-to-market instantization process. You also expect each shake to taste the same as the last and your next. That's the kind of consistency ON delivers.

HISTORY & HERITAGE

Optimum Nutrition is legendary for both quality and innovation. In addition to producing the world's best-selling whey protein, ON's Gold Standard 100% Casein™ introduced slow-digesting nighttime protein to the weight training world and Essential Amino Energy™ created the anytime energy category in sports nutrition. When technology makes advancements possible, ON will be the company bringing it first to your shaker cup.

Never tried casein before so I figured I'd go with ON brand. I really enjoy the product! I take it before bed on workout days (I go to the gym in the morning) so it helps my body recover later in the day. I wake up feeling a little stronger and less hungry. I have noticed slightly quicker mass growth since I've started using it, which makes sense because I'm essentially doubling my protein supplement intake (I take ON brand whey shortly after a workout). The Creamy Vanilla tastes great mixed with milk. My only complaint is that it is very thick so it takes longer to shake in my Blender Bottle; to compensate, I use 10oz of milk instead of 8oz like I do with whey. I'm only rating it an 8 because I have no other casein products to compare it to and I've only been using it for a few weeks, but so far so good! Will buy again.

I really like this product. I have been using the chocolate supreme and just recently ordered the banana cream which is absolutely delicious. The Mint Chocolate Chip is really good also. This fills you up a bit more than the Whey Protein, but I guess it should. Also doesn't blend as well as whey, but that may be Casein in general.

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.
