Love this product. Not heavy at all and doesn't give you that bloated feeling a lot of protein powders give. I've been having it in my daily smoothies and ive lost 9KGs, its the only part of my diet and exercise routine that ive changed so its definitely works well as a part of a balanced diet. Very smooth, dissolves easily and doesn't leave a milky taste. Vanilla is definitely my favorite and goes with everything - unfortunately it was out of stock so had to try the chocolate, took a while to get used to the taste but otherwise great as well. Definitely recommend.

Ignore the 3 star review. Are there “cleaner” proteins out there, yes. Does this one have a couple more ingredients than them, probably. Does that matter to you?… Decide then buy what you want.This is probably the best chocolate protein I’ve had in the 20 years of drinking different powders. Mixed alone in water it’s delicious. Make a full on “shake”…fuggetaboutit.Mixes great.Above all the other praises; for myself and many clients I’ve recommended this to, none have experienced any gastrointestinal distress common with people with milk protein sensitivity. This is a result of an obvious high quality level of “isolation” of the whey protein.Try it and you’ll understand why it’s always out of stock.

A great helper for recovering strength after a workout. I like the taste, too. Large package and the product lasts a long time

Great post-workout product
22 August 2021

Overall great product. I find it a bit too sweet to drink mixed in only water (it tastes like melted vanilla ice cream), however, I mix it in water and then add it to my greek yoghurt & berry smoothie. It dissolves well in water if you stir it and leave it for about a minute- before drinking or mixing it in a smoothie. I much prefer the isolate to whey, as it is much easier on one's stomach. Furthermore, the product does what I want it to do- it assists with post-workout muscle support and hitting my macro targets. Overall great product.

Great service, great product!

Every time I order from Get Yok’d, the order is shipped quickly and the customer service is terrific!! I love Optimum Nutrition’s products but especially the Gold Standard 100% Isolate. The taste is great by itself or in a smoothie or shake. My favorite part is that the protein mixes well. It doesn’t taste too sweet, which helps the flavor of my shakes and smoothies.

No Reason to Try Anything Else
12 August 2021

This is the first protein supplement I've tried and am unlikely to try anything else. I like the versatility of the product and results I am experiencing. I purchased the Vanilla and use it in multiple ways- shaken with milk for my cereal in the morning, shaken with oat or macadamia milk for a quick drink, and added to my fruit smoothies. My boyfriend says it tastes like marshmallows. Along with the great taste, I am finding that this product helps me with progressive overload. My muscles are able to push it a little more since I've started using this regularly.

Vanilla Preferred, Good Product
1 June 2023

I've had both the vanilla and chocolate from ON and I definitely prefer the vanilla, by far. The chocolate variation tasted quite off to me, but I'm particularly sensitive to some chocolate flavors, so your individual mileage may vary in this case. The vanilla mixes smoothly, leaves no chunks, and seems to digest and absorb without much problem. The flavor is fairly mild vanilla. Subdued sweetness. Coming from more typical whey concentrate, I've been pleased with the results offered by Isolate. At least for me personally, it seems to provide a better experience. The flavor here won't blow you away, but it plays well with water which is all I can really ask.

Wierd aftertaste
10 November 2018

I purchase this direct from ON in the Strawberry cream flavor. I mixed it with 8oz of water in my shaker cup and noticed it failed to mix well leaving clumps in the drink. The initial taste was ok, but the aftertaste was very chemically. The second time I mixed it I used almond milk and a personal blender. This resolved the clumping issue, and it did taste better with the almond milk, yet still had the same strange after taste. The third time I used whole milk and the blender. This was actually the best way to mix this particular powder. Still, it had a strange aftertaste to it, albeit not as noticeable as in previous variations. I did use the entire container switching between this and two other brands. I was glad when I finished the tub and would not consider ... MoreI purchase this direct from ON in the Strawberry cream flavor.

I was glad when I finished the tub and would not consider buying this again, especially in the strawberry cream flavor. I will admit that about halfway through the tub I started to crave the taste of this. I am not sure if it was due to the chemical sweeteners or what it was. However, I will pass on this brand in the future and go back to the other two brands that are all natural.
