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.

    Clean Gainer

    I love how the calorie count is really low and allows you to take in as MUCH of the healthy protein at once. Great product and I love the price as well. Great Bang for your buck

    The best there is

    The chocolate clean gainer is the best protein I have found. As a D1 athlete, my school feels safe with me taking it. It taste so good. Very easy to drink. Will never go to any other brand after having this product

    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

    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”
