SLOW-DIGESTING PROTEIN


Right before or after training, rapidly digesting whey protein helps start recovery, a process that can take up to 48 hours. Between meals and before bed, when nutritional support won’t be available for a while, casein protein can help provide longer lasting amino acid support. Micellar casein is pH sensitive and gels in the acidic environment of your stomach. As a result, it can take longer to be broken-down compared to whey and other proteins. ON's Gold Standard 100% Casein was the first all-micellar casein and remains the best seller.

Beyond The Basics

>> 24g of Anti-Catabolic Micellar Casein
>> Nearly 5g of Naturally Occurring BCAAs per Scoop
>> Nearly 5g of Naturally Occurring Glutamine and Glutamic Acid per Scoop

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.

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.

Doggos are excited but...
Size: Large, Color: 9 Packs
My dogs are ecstatic about their new ropes. But they're big and aggressive chewers. These ropes are thinner than the pictures made them look. I'd say they're appropriately sized for dogs up to 35 lbs - and not as great for the large breeds show in the pictures.

My dogs loved this toy!
Color: Orange & Blue
My dogs absolutely loved these! The quality is actually good and the price for two of them is fair! Surprisingly the durability is more than I expected my aggressive chewer hasn’t completely destroyed it!

Tough toys!
Color: Orange & Blue
We have 2 deogs, a large Aussie and a small terrior. The little guy is very hard on toys. Few last a full day. We have thrown away hundreds of $ worth of toys, We have had these for a few months, and he has not managed to destoy them yet. They get played with a lot because he has very few toys. I keep trying to find toys which will survive this dog. He hjas even destroyed Kong toys which are pretty tough, but has not destroyed these. I wrote this review as I cam back to order more toys from this company, because it is great to have some which can stand up to his abuse.

Great dog toys
Color: Orange & Blue
These Zeaxuie octopus dog toys are a huge hit with my pup! The crinkle and squeaky features immediately grabbed his attention, and he’s been happily chewing and playing with them ever since. I love that they’re stuffing-free, so I don’t have to worry about any mess. They’re the perfect size for small to medium breeds and seem very durable. These toys have kept my dog entertained for hours – definitely a great purchase!

Our dogs love these
Color: Orange & Blue
We have two rough collies that love to play fetch, tug, and ragdoll. We decided to add these to their play toys. Since getting them they have been ignoring their ducks and going straight for the octopus. We just got them so can’t say much about durability yet but they have been playing with them for hours and still look brand new. Love giving our dogs choices so we can ask them for certain animals to fetch. Love the non-stuffing and the crinkle.
