Worth the extra $$

Tastes goo. Builds muscle. Healthier than 'non-isolate'

Bob TVerified Buyer

Rich chocolate taste, dissolves fast and completely, fulfilling

Wanda GVerified Buyer

Jeremy AVerified Buyer

Gnc & ON protein powders are great

It's GREAT easy to mix the taste is good

John DVerified Buyer

Tastes great and works well for my workout recovery.

Lawrence MVerified Buyer

Too Strong in Flavor

The flavor, while rich in taste, does not blend well with any fruit because the taste overpowers the fruit regardless of how fruit is used.

TONY CVerified Buyer

Tasty and yet effective Whey Isolate

I am a vanilla fan and this flavor is the best.

Nitin KVerified Buyer

Very pleasant taste when I mix with cold water. After drinking it in the morning after my workout I feel great all day. Very happy with the time between ordering and delivery too. Pricey but, definitely outperforms the other less expensive powders I've tried. As long as I continue to be able to afford it I'll keep ordering more. Thanks for a fine product.

Daniel FVerified Buyer

Exceeded my hopes

VISA CVerified Buyer

Gold Standard

I've always used Optimum Nutrition protein. This Isolate mixes easy and tastes great.

Shane BVerified Buyer

Great protein supplement

I really like this product. I find it mixes well. I typically have a smoothie every morning and this protein powder is perfect in it. Sometimes after weightlifting I'll just have a glass of water with this in it. I like the flavor but I only use the vanilla so I can't comment on the other flavors. I've tried cheaper alternatives but keep coming back this one. Highly recommended.

Robert HVerified Buyer

Brendan BVerified Buyer

Would recommend

Tastes awesome and mixes way better than other protein powders I've bought

Dylan dVerified Buyer

It had sucralose, which some studies are showing degenerates DNA and spikes Insulin?Maybe a Stevia version soon

Alex SVerified Buyer

Easy to buy, fast delivery, really good taste?It was really a great purchase!

Ana AVerified Buyer

Worth it

The chocolate tastes great, not too overpowering and not too sweet. I little less sweet could be better imo, but that's my preference. A larger size and cheaper would also be a plus of course, or a sustainably sourced container would be even better.

William RVerified Buyer

Vanilla Preferred, Good Product

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.

Jonathan WVerified Buyer

Great taste, Great ingredients!

Best tasting protein powder I've ever had. Good clean ingredients. I will definitely be buying more!
