Overall I really like the protien itself. The birthday cake flavor, however, no good. For one it’s extremely sweet, and doesn’t taste good. I am a lover of birthday cake flavored anything, but this flavor just isn’t good. Don’t get the birthday cake. I’ve had a cake batter flavor by another company that was amazing and I was hoping Dymatize’s would be good too, but no.

Iso100 is indisputably a flavoring masterpeice; most recently, chocolate peanut butter has won me over b/c the peanut flour w/chocolate is perfectly balanced and sweetened. Peanut Butter is also very good but the chocolate just compliments it very nicely; Gourmet chocolate is another fav. due to the flaky chocolate texture (esp. when chilled/slightly frozen). I highly recommend it in milk to everyone of all ages as the hydrolyzed whey is top tier. Iso-100 Clear Blue Raspberry tastes very refreshing especially when chilled, exactly like a raspberry lemonade! I was able to drink this in between powdered (milk) protein shakes when eating food which provided me with valuable extra aminos. Everyone should try this delicious whey isolate given its exceptionally clean profile and ease of ingestion (a much better alternative to typical sports drink especially if you have electrolytes to add in!)

  • 9 Cookies and Cream

The top of the line for isolate protein in the marketplace. Only 110 cals per serving great for cutting or bulking. Taste is second to none and is typically more full bodied than other isolates. Would reccomend to anyone!

  • 9 Birthday Cake

Don’t know how anyone cannot like this product. Great profile, mixes well and taste great. IMO the thing that separates Dymatize from other companies are their amazing unique flavors. Birthday Cake is fantastic. Brought me back to the days of having a birthday are Chucky Cheese and blowing out me candles.
