    Blend it with some ice and oat or soy milk and tastes like a Wendy's Frosty!

    Campfire s’mores clean gainer

    Posted by Frankie Morgan on Mar 5th 2022

    Taste is great, product is packed with great ingredients, I’ve been able to pack on over 10 solid lbs of muscle since starting it. (2 12lb bags) my only complaint would be the new shape of the scoop. Doesn’t make it very easy to dump in my shaker cup.

    Great Product!

    Posted by Casey Tanner on Feb 15th 2022

    I've had Rival Nutrition's Clean Gainer in the Cookies & Creme flavor, Cinnamon Toast Cereal flavor, and Chocolate Peanut Butter flavor. All three flavors taste great, but the Cookies & Creme one is my personal flavor. What I like about the Clean Gainer product is that it's filled with great macro ratios, little sugar, contains a more natural carb blend, and mixes very well. Seriously, this is one of the better, if not the best, mixing mass gainers as there is zero clumping.

    Best quality calories for adding mass

    Posted by Todd Stukenberg on Dec 28th 2021

    Very high quality sources of calories to add mass. Using it to put on real functional weight for a 16-17 year old athlete. Has played a key role in adding 20 quality pounds in 15 months
