Very good whey, but the chocolate flavor is disgusting

Probably the best protein powder I've had in a long time. It dissolves easy and tastes good enough. i am not looking for taste. i am more interested in the quality (1) digestion, (2) texture, and (3) price. It's all good. I usually mix this with Synth whey protein and it's just great. I highly recommend this product.


Great protein product! Mixes very well , no chunks! This is delicious mixed in with oatmeal!! One of my favorite breakfasts! I also drink 1 scoop of this post workout. The best thing about this product is that it doesn't mess with my digestion and stomach. Usually I am very sensitive to proteins, but I have no issues with this one. Highly recommend this product.

Tried samples of Chocolate Peanut Butter AND Peanut Butter from Both were outstanding, but I preferred the Choc PB combo. I ordered a 5 lb tub and love it. Very good mixability, taste, texture etc. This is a clean isolate/hydrosolate with low calories, low carbs, BUT excellent flavor and texture (hard combination to find). It is very good with just water, which is rare. But it is AMAZING with almond/coconut milk, some natural peanut butter, 1/3 banana etc! I am a big fan of all Nutrabio products and am currently using a 5 lb tub of their Choc Peanut Butter Isolate as well. It has a similar ingredient profile, similar carbs/fat/cals, but the taste and texture are not as good. I see why Dymatize Iso-100 has won so many awards. So far, it is the best Isolate I have tried.
