I usually order Muscle Pharm Casein, because its low sugar and sodium and it provides 28 grams of protein, but its on backorder, so I ended ordering this as a replacement. It tastes ok, but you can really taste the sodium and sugar in it the product, and it makes me really appreciate the pharms product. Ill most likely go back once theres a supply. I'm sure theres some benefit of this protein, but compared to others, I'm not impressed. Don't understand the need for added sugar and sodium.

Just started using the casein at night and I am impressed. No hunger before bedtime for me and it seems to be working great. Just ordered a bigger size the other day.

If I mix it with my silk vanilla cashew almond nut milk it turns into a pudding!

This is my favorite casein. I Use it as a base for my protein pudding and protein (pretend) cookie dough

I get best results with water in a shaker and add milk after it's dissolved. Great taste and easy to digest even when drinking it right before bed. If you haven't tried casein for an overnight protein boost, try this one.

Tastes awesome with whatever you mix, however the issue is if you mix it with water, clumps usually are created causing a very displeasing shake (consistency wise). I've heard ways that people try to counter act this but have yet to find a stable solution

I've tried a few casein products now and so far this is my least favorite. The flavour is bland and it doesn't mix well. It does however do its job, so I will for sure finish it off.

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.
