  • Whey Protein Isolate (WPI) Main Ingredient
  • Whey Protein Microfractions from Whey Protein Isolates & Ultra-Filtered Whey Protein Concentrate
  • Over 4 Grams of Glutamine & Glutamic Acid in Each Serving
  • More Than 5 Grams of the Naturally Occurring Branched Chain Amino Acids (BCAAs) Leucine, Isoleucine, and Valine in Each Serving
  • The “Gold Standard” for Protein Quality



Whey Protein Isolates (WPI) are the purest form of whey protein that currently exists. WPIs are costly to use, but rate among the best proteins that money can buy. That’s why they’re the first ingredient you read on the Gold Standard 100% Whey™ label. By using WPI as the primary ingredient along with premium ultra-filtered whey protein concentrate (WPC), we’re able to pack 24 grams of protein into every serving to support your muscle building needs after training. ON’s attention to detail also extends to mixability. This superior quality powder has been instantized to mix easily using a shaker cup or just a glass and spoon. There’s no doubt that this is the standard by which all other whey proteins are measured.

    Tastes great. I will either make a shake or mix it in my morning oats. Both result in great tasting mixtures. Gold standard always has good flavors but this one has so far not bored me. Would definitely recommend if you like mocha. Mixes well with iced coffee too 🙂

    Added with almond milk and you have a nice creamy milky mocha flavor protein shake

    I love this stuff. I’m not a body builder or workout fiend, but wanted a convenient meal replacement. This is perfect for busy mornings or those times I just don’t feel like having a heavy meal. I’ve not tasted other flavors but this has a very good chocolate flavor. I especially like it mixed with skim milk.

    I have been using this product for years with good results. The product arrived with no problems on time. Each flavor I have tried has been good, with some being better than others. Cake Batter flavor has been one of my favorites, and it taste good mixed with water or milk.

    Been using Gold Standard since 2007ish. It continues to deliver great results. Every protein is great, some are just not great for your body. If this doesn’t work for you, maybe its not what your body wants. But Gold Standard has been the top of the market since I can remember for a reason. Its a very good product with a very good company.

    I mix the birthday cake flavor with my vanilla Greek yogurt to get extra protein. Tastes great. I look forward to it every morning and sometimes as a snack when I have a sweet craving.

    Taste really good, a light taste and a nice prominent vanilla flavor. The cake taste is true it has that after taste of confetti cake from pillsbury so it kinda hits your sweet tooth too. It doesn’t have that artificial perfume aroma some cake batter flavored have and I recommend this is your a vanilla person.

    I’m so pleased with this protein powder!! The taste is fantastic (I got the birthday cake one) and doesn’t have that weird artificial sweetener taste that some powders do. It blends beautifully. I’ve blended it by shaking the bottle and in a blender, and both worked great! I’ve used it in baking as well. I just can’t say enough good things about this. If you’re picky about flavor and texture, this is the protein powder for you!

    I ordered the coffee flavor. I mix 1 scoop (32g) WPI with 8 oz of oat milk and the flavor is outstanding. After 20 seconds of shaking you get a well mixed, homogenized mixture. The taste is phenomenal and tastes like actual coffee with zero aftertaste. If you mix well, you get a frothy mixture which drinks/tastes like a cappuccino. I tend to drink mine in literally 10 seconds. It is that good. (Taste/flavor/mixability may change with different milks. You get optimal mixability with oat milk/soy milk)

    I’ve tired a lot of different protein powders and the Mocha Cappuccino is definitely one of the best flavors you can get. No aftertaste of any kind of great with just water or milk if you want to use that, but I just use water, won’t make you feel full and not hard to finish like some can be a struggle to get down

    I absolutely love this product it blends incredibly well and water a prep it in the morning with about 12 ounces of water and a few ice cubes and drink it just after lunchtime and a shaker. The flavor is good it is not grainy at all and it’s satiates my hunger.

    The BEST protein I’ve ever purchased. Dissolved without a blender and in water. Tastes amazing and just feels clean and good. I couldn’t care less for the birthday cake flavor. Had to sift out all the sprinkles because I couldn’t stand them

    This is by far the best protein powder I’ve used to date. All other powders I’ve tried have a funny or nasty after taste that I just assumed was the protein itself but not this protein powder. The smell alone set it apart from other powders as this had a real cookies & cream scent. But the taste waa the big kicker for me. Tastes great w/ just plain water. I use protein drinks as a meal replacer & 2 scoops of this holds me over for a long time

    On Nutrition is making some of the the best tasting and easily digested protein lines out there. Rocky Road is definitely a winner with just a hint of the marshmallow taste. Experiment and the flavor gets even better. A handful of frozen organic raspberries puts it over the top. An my new found favorite: Mix up in a Magic Bullet scoop and a half of Rocky Road, low fat milk, half banana, two spoons of peanut butter and some ice chips! FREAKING INSANE tasty!

    Top protein in Canada!

    I was surprised to find that the cookies and cream flavor is highly divisive. I really like it, but I use 8oz of milk, not water. I also use a stick blender to not only mix the powder, but whip a great deal of air into the drink, which thickens it somewhat into a consistancy more like a shake. This creates, in my opinion, a much more pleasant mouth feel and enjoyable drinking experience.

    I’ve been using this protein powder for years in my oatmeal. I mix it with flaxseeds, chia seeds and sliced almonds. Delicious.

    Very happy with this product. I got Rocky Road based on another reviewers comments. He said it was far and away the best flavor, with the extreme milk chocolate not far behind. I think I’ll try that one next. Of note for chocolate lovers, he said the ‘double chocolate’ (i think it’s called that anyways) is terrible!

    This is now my favorite flavor with vanilla being second. The quality is the best, BCAAs included. I’ll be trying some other flavors.

    Great protein powder. Product came as advertised. The Rocky Road flavour is great (like a chocolate vanilla mix). It dissolves well in water with a stir and shake. I have also had Double Chocolate and Strawberry in the past (because these 3 flavours seem to have the least amount of ingredients, without the other stuff like creamer/additives). All 3 are awesome!
