To pack on serious size, you need to consume more energy than you burn. A number of variables need to be factored in, but 3,500 calories per pound of added body weight is a commonly referenced estimate. True hard gainers may need even more. In a world of fast food, finding extra calories isn’t hard. Getting quality, protein-rich calories to back-up your gym time? Now that’s a different story.

With a killer combo of full-spectrum proteins, eight energizing carb sources, and essential fats, CLEAN GAINER™ is high-octane nutrition (over 560 calories worth) that fuels the intense needs of world-class athletes as well as those who aspire to be. Factor in the no banned substances and it’s a MASSIVE winner.


Add 2 scoops of CLEAN GAINER™ to a large glass or shaker cup filled with 12-16 ounces of cold water. Stir or shake for a few seconds until powder is fully dissolved. Enjoy. Tip: Replace the water with low-fat milk to boost the calories and protein content. For greater mass potential, try blending in high-energy ingredients like peanut butter, flaxseed. MCT, or olive oil, and/or coconut pieces.


After workouts or before bed.

    Posted by Jeffrey Mcfarland on May 8th 2020

    best gainer I've used, I use it 1 to 2 times daily, taste is great and I've put on a few pounds in the last few weeks with exercise. Will continue to buy this product for sure. Just reordered 2 more 12lb bags.

    This stuff is amazing. It has the best taste. It breaks down good so no chunky or gritty stuff. Rivalus makes the best products

    Great Product

    Posted by Krystol Kennedy on May 6th 2020

    A friend recommended this brand when I spoke to him about my son needing a weight gainer protein to help him bulk up. I ordered the Clean Gainer in Creamy Vanilla because I felt good about the ingredients.
    My picky son said it's the best tasting protein he's ever taken and I have to say we could both tell he put on weight after using this for just one week. I would recommend this to anyone

    Nutritionally excellent, unparalleled

    Up front, I'm not a bodybuilder - just a normal guy who works out but is concerned about what I'm putting in my body. To me, absorption and a more natural mix are important, so I supplement the mix with HCl and pepsin, and it always works well: the protein is better absorbed, my digestive system's happy and I know I'm getting much more - that's good for my body - than any other gainers I've seen so far. Thanks, Rivalus.

    Clean Gainer

    Very impressed with this product, did a good amount of research and this product definitely delivered. Double fudge flavor tastes like hot chocolate and it doesn’t make me feel gross like a lot of other mass gainers do. I love the fact that the carb complex is made of whole foods rather than a bunch of sugar or other processed stuff. Will more than likely be buying this every year for “bulking season”

    This product is effective and is a better buy than like products. Using Rivalus gainer in combination with the right diet, you will see results.

    Hands down, the best gainer I’ve ever used. Taste, mix ability, quality, ingredients. 10/10. Cinnamon Toast Crunch is the best flavor too. Will be using all 2020

    Great Taste

    Posted by Matt on Oct 25th 2019

    I have tried many protein powders and this is by far the best tasting formula. This formula is also composed of a much cleaner mix of ingredients in comparison to other powders.
