Why Trust Fortune<\/p>\n
Our team of expert testers has tried hundreds of the most popular supplements on the market today, using our comprehensive supplement testing methodology <\/a>to find the best products for all folks.\u00a0<\/p>\n Best Mass Gainers of 2025<\/p>\n Best Mass Gainers Comparison Table<\/p>\n Best Mass Gainer Overall: Transparent Labs Mass Gainer<\/p>\n Transparent Labs Mass Gainer Our Thoughts on Transparent Labs Mass Gainer<\/p>\n Transparent Labs Mass Gainer earned our pick for the best overall mass gainer because it includes high-quality ingredients and transparent labeling. Each serving provides about 770 calories, over 50 grams of grass-fed whey protein, and clean carbohydrate sources like oat, tapioca, and sweet potato, making it ideal for those who want to gain mass without excessive added sugars or low-quality fillers.\u00a0<\/p>\n This formula stands out for its inclusion of 3 grams of creatine monohydrate<\/a> to enhance muscle growth and recovery, and for using natural sweeteners like stevia and monk fruit\u2014avoiding artificial ingredients like sucralose. The product is third-party tested, non-GMO, and has a fully transparent label, allowing users to trust what they are getting in every scoop.<\/p>\n Pete tested Transparent Labs Mass Gainer, rating it a 5 out of 5 for first impression. \u201cIt comes in a very large white plastic container which is about twice as large as your standard two-pound protein powder tub,\u201d he noted. He observed that the label is informative and easy to read, and the container opens and closes easily. That said, this tub is pretty big, so you\u2019ll want to clear some cabinet space.<\/p>\n When mixing the powder along with water, Pete found that the product didn\u2019t dissolve within 60 seconds, rating it a 1 out of 5 for mixability. \u201cThe texture was very clumpy and there were visible chunks,\u201d he said. He shook it for another 60 seconds, but it still didn\u2019t dissolve. Generally, mass gainers are pretty dense, so Pete recommends using a blender to mix this product, especially since the serving size is two scoops.<\/p>\n Pete rated the taste of the flavor a 3 out of 5, and a 5 out of 5 for sweetness: \u201cThe flavor I tested was sweet vanilla, and it was true to its name\u2014the supplement was very sweet. The shake was thick, and I would compare the taste to a melted vanilla ice cream,\u201d he said. Pete also said he probably wouldn\u2019t choose this flavor to drink regularly, as it has a strong stevia flavor. He does like the product as a mass gainer, since it provides over 700 calories per serving and 50+ grams of protein.\u00a0<\/p>\n Our tester didn\u2019t experience any digestive issues with Transparent Labs Mass Gainer, despite the strong stevia aftertaste. Overall, he said: \u201cI like the product for what it\u2019s intended for, despite not loving the flavor. It\u2019s important to note that a mass gainer needs to be consumed in addition to what someone is already eating. If your goal is to gain weight, then this shouldn\u2019t be used as a meal replacement powder.\u201d<\/p>\n Best Budget Mass Gainer: Nutricost Mass Gainer<\/p>\n Nutricost Mass Gainer Our Thoughts on Nutricost Mass Gainer<\/p>\n Nutricost Mass Gainer is our top budget pick because it offers a strong nutritional profile\u20141,220 calories and 50 grams of protein per serving\u2014at an accessible price point. The carbohydrate source is maltodextrin, which is common in mass gainer supplements. Maltodextrin is rapidly absorbed by the body, making this supplement ideal for post-workout recovery. The product has 50 grams of protein from whey concentrate, and also contains 2,500 mg of L-glutamine and 2,500 mg of creatine per serving, which creates a great value for a mass gainer supplement.<\/p>\n Pete tested this product and rated it a 3 out of 5 for his first impressions. Nutricost\u2019s Mass Gainer supplement comes in a large plastic container with a net weight of nearly seven pounds. The label is straightforward and easy to read, clearly showing the calorie count and protein per serving. This comes in a pretty large container but the lid is easy to open and close, Pete said.\u00a0<\/p>\n Of the mixability of Nutricost\u2019s Mass Gainer, Pete said: \u201cI tried using my large 32-ounce shaker bottle to mix this mass gainer and it just wasn\u2019t practical.\u201d <\/p>\n The serving size is three scoops, which filled Pete\u2019s shaker bottle about halfway with powder, and after adding water and shaking for 60 seconds, there were still large chunks of unmixed powder. \u201cFor this mass gainer supplement, I would recommend blending for a smooth consistency and using more than the suggested 24 oz. of water unless you like a thick shake,\u201d Pete said. Our team did have to give this product a 1 out of 5 for mixability but this is pretty common for mass gainers in general.<\/p>\n Pete loved the taste of this mass gainer, rating it a 5 out of 5. \u201cI tested the chocolate peanut butter flavor, and it tasted great. I was able to taste both the chocolate and peanut butter flavors and the shake had a smooth and creamy consistency after blending,\u201d he said. Pete found the instructions produced a shake that was a little too thick for his liking and suggested some modifications: \u201cIf I was to use this supplement daily, I would use more water, about 28 to 32 ounces to make a thinner shake. I did really enjoy the flavor, and this would be something I would drink regularly,\u201d he said.<\/p>\n Our tester also noted that he didn\u2019t experience any digestive issues or negative side effects after consuming this product, adding: \u201cI was full after the full three-scoop serving size and it was a good two to three hours before I was hungry again for another meal.\u201d<\/p>\n Best Vegan Mass Gainer: Huel Black<\/p>\n Huel Black Our Thoughts on Huel Black<\/p>\n Huel Black Edition is our pick for best vegan mass gainer, as it\u2019s packed with 40 grams of plant-based protein and 400 calories per serving. While it\u2019s marketed as a meal replacement, it also works well as a mass gainer for those seeking to add healthy calories and protein to their diet, making it ideal for hard gainers and athletes. Thanks to its well-balanced macros, full spectrum of vitamins and minerals, and standout taste (our tester scored it a 5 out of 5 for flavor), Huel Black Edition is a top choice for anyone prioritizing both nutrition and taste in a mass gainer.\u00a0<\/p>\n Pete tried Huel Black, rating it a 5 out of 5 for flavor (he tested the vanilla), saying: \u201cThe taste is pleasant, especially for the 90-gram serving size and thick consistency. You can taste the vanilla, and it\u2019s a very moderate level of sweetness with no aftertaste.\u201d\u00a0<\/p>\n Our tester found the texture to be slightly gritty, likely due to the flaxseed content, though he said this wasn\u2019t off-putting and actually added to the shake\u2019s character. He\u2019d have no trouble drinking Huel Black regularly, praising it as a well-rounded meal replacement suitable even for daily breakfast thanks to its robust supply of vitamins and minerals. Like a greens powder<\/a>, for instance, this formula delivers plentiful beneficial nutrients like omega-3 fatty acids<\/a>, medium chain triglycerides (MCTs)<\/a>, and EGCG<\/a> from green tea extract.<\/p>\n Pete rated Huel Black\u2019s mixability as a 3 out of 5. \u201cThere were a few very small chunks after mixing it in the shaker bottle for 60 seconds,\u201d he said. But, according to Pete, the flaxseed used in the mix can be visibly seen and tasted. The result of the formula being combined is a \u201cthin, oatmeal-like consistency. For those who create their own meal replacement shakes at home using protein powder, peanut butter, seeds, and oats, this will feel very similar to that,\u201d he said.<\/p>\n He didn\u2019t experience any adverse effects or digestive issues when testing this product, rating it a 5 out of 5 for side effects. Overall, he enjoyed the taste, consistency, and recommends using a blender to mix the product fully.<\/p>\n Best Mass Gainer Protein Powder: Crazy Nutrition Mass Gainer<\/p>\n Crazy Nutrition Mass Gainer Our Thoughts on Crazy Nutrition Mass Gainer<\/p>\n Crazy Nutrition Mass Gainer is our pick for the best mass gainer protein powder because it includes protein from a blend of whey protein concentrate and milk protein concentrate, providing a robust amino acid profile for muscle growth and recovery. Our team also likes the whole-food-based ingredients, balanced macros, and easy digestibility\u2014making it ideal for athletes and hard gainers aiming to build muscle without excess sugar or fillers. This formula includes digestive enzymes to enhance your body\u2019s absorption of nutrients. However, if you\u2019re having digestive difficulty, you may want to consult a doctor or consider a probiotic supplement<\/a>.<\/p>\n Pete tested Crazy Nutrition\u2019s Mass Gainer and rated his first impression of the product as a 3 out of 5, saying: \u201cThe packaging is a large yellow resealable bag, with black lettering. The words are easy to read and while not difficult to open, the bag was cumbersome to close properly.\u201d<\/p>\n Our tester rated the mixability of this product a 1 out of 5. \u201cThe product is mostly dissolved after shaking for sixty seconds,\u201d Pete said. \u201cThere weren\u2019t any large visible chunks, however, when drinking the shake had a grainy consistency. I tried shaking for an additional sixty seconds but the grainy consistency remained,\u201d he said. Pete also noted that the four-scoop serving size is a lot to fit in a standard shaker bottle. He recommends using a blender to mix this much powder smoothly with the liquid of your choice.<\/p>\n Pete felt the taste of Crazy Nutrition\u2019s Mass Gainer was just okay, rating it a 3 out of 5. \u201cThe flavor I tested was chocolate, however, I didn\u2019t find this supplement to have a very strong chocolatey taste. When drinking the product, it tastes fairly sweet at first, but then you get a strong oat milk-like flavor. This is because the carbohydrate source in this product is oat flour,\u201d Pete said. He added that he didn\u2019t experience any digestive issues or negative side effects when testing this product.<\/p>\n Overall, Pete thinks this is an effective mass gainer. \u201cThe full four-scoop serving size provides about 500 calories per serving and 40 grams of protein,\u201d he wrote. \u201cThis number of calories in addition to someone\u2019s normal dietary routine would be enough to help them put on weight. Note that they do use sucralose to sweeten this product, however, there aren\u2019t any artificial flavors or colors.\u201d<\/p>\n Best Mass Gainer for Bulking: Optimum Nutrition Serious Mass<\/p>\n Optimum Nutrition Serious Mass Our Thoughts on Optimum Nutrition Serious Mass<\/p>\n Optimum Nutrition Serious Mass was chosen as our top pick for best mass gainer for bulking because it delivers a significantly higher calorie count per serving than most mass gainers on the market\u2014packing 1,260 calories per serving, including 50 grams of protein, and over 250 grams of carbs into a single shake. This makes it the ideal choice for advanced athletes looking to consume a calorie surplus.\u00a0<\/p>\n Pete rated this product a 3 out of 5 for his first impression: \u201cThis mass gainer supplement comes in a massive bag and contains a whopping twelve pounds of powder\u2014definitely not travel-friendly. The packaging is easy to read, and I really like the resealable zip-lock closure that makes it easy to open and close. A large scoop is included inside the bag.\u201d<\/p>\n When rating the mixability, Pete gave it a 1 out of 5. \u201cThe sheer serving size of this supplement would make it pretty much impossible to mix in a standard shaker bottle,\u201d he said. \u201cI used a blender and twenty-four ounces of water to mix the powder, and the shake was fully dissolved but had a thick consistency.\u201d<\/p>\n Pete loved the taste of Optimum Nutrition\u2019s Serious Mass, rating it a 5 out of 5. \u201cI tested the vanilla flavor and was very impressed. It had a creamy vanilla taste and just the right level of sweetness. After blending, the shake had a smooth consistency, but with the full two-scoop serving size and twenty-four ounces of water it was very thick.\u201d He said that if he were to use this product on a daily basis, he\u2019d probably split the drink into two\u2014a single scoop shake in the morning and another in the evening.<\/p>\n Pete added, \u201cI felt fine after drinking the shake and didn\u2019t experience any digestive issues. That said, I was very full after drinking the entire shake and wouldn\u2019t suggest consuming it before a workout.\u201d<\/p>\n Of this supplement overall, Pete said, \u201cAs a mass gainer, this will definitely get the job done. The full two scoop serving size contains 1260 calories, 253 grams of carbs, 50 grams of protein, and just 5 grams of fat. It\u2019s important to note that for this supplement to be effective in terms of promoting weight gain, the user would ideally consume this shake in addition to what they are currently eating.\u201d<\/p>\n What Is a Mass Gainer?<\/p>\n A mass gainer is a high-calorie dietary supplement specifically designed to help you gain weight and build muscle, especially for people who have difficulty meeting their calorie and macronutrient needs through whole foods alone. What sets mass gainers apart from standard protein powders is their comprehensive nutrition profile: rather than supplying just protein, mass gainers provide a mix of proteins, complex carbohydrates, and healthy fats, usually in a ratio of 2:1 or 3:1 carbs to protein, with some products offering upwards of 1,000 calories per serving. Many also include dietary fiber, vitamins, minerals, and nutrients like creatine or digestive enzymes.<\/p>\n Mass gainers work by creating a calorie surplus, which is essential for gaining weight and supporting muscle growth. Each serving provides a concentrated boost of calories, carbs, and protein to fuel workouts and jump-start post-exercise muscle repair. Carbohydrates supply sustained energy, while high-quality protein supports muscle protein synthesis and recovery.<\/p>\n Mass Gainer vs. Protein Powder<\/p>\n Protein powders and mass gainers are both popular supplements for muscle-building, but their nutritional profiles and intended uses set them apart. Protein powders\u2014especially those based on whey\u2014are designed to maximize protein intake with minimal extras, often delivering 20\u201330 grams of protein per serving with very little fat or carbohydrates, and typically only 100\u2013150 calories per scoop. The primary function of protein powder is to support muscle recovery and lean muscle growth, making it the go-to option for those looking to build or maintain muscle without significant increases in daily calorie intake.<\/p>\n Mass gainers are formulated with the explicit goal of calorie surplus, including not only protein but also a much higher proportion of complex carbohydrates and fat. A single serving can provide anywhere from 500 to over 1,000 calories, with a balanced mix of protein (20\u201350 grams), carbohydrates, and fats, designed to help users achieve the excess caloric intake required for weight and muscle mass gain. While protein powders are best for those focused on protein and lean muscle, mass gainers are all about delivering a full spectrum of macros, making them ideal for people with high energy needs or those who struggle to gain weight.<\/p>\n That said, if you are looking to gain weight or muscle mass, our team always recommends prioritizing a balanced whole-food diet. However, for some folks, it can be hard to consume enough calories through whole foods. In this case, a mass gainer can be a helpful tool.\u00a0<\/p>\n How We Tested and Selected the Best Mass Gainers<\/p>\n We tested and evaluated mass gainers and scored them on a scale of 1-5 for factors such as first impressions, easy-to-follow directions, taste, mixability, side effects, and value. Our testers evaluate the products based on their own individual experiences and preferences. We then review their testing feedback and data to share our findings and recommendations with you.<\/p>\n Taste and Texture<\/p>\n Flavor is a big part of our testing process. We ask our testers to provide feedback on the taste, texture, and pleasantness of the flavor for each mass gainer. We rate sweetness on a scale of 1 to 5, based on how strong the sweetness is. A score of 5 is best-tasting, 1 is not drinkable. We also consider texture, and ask our tester to record any grittiness, clumps, frothiness, or conversely, smoothness and creaminess, when tasting the mass gainer drink.<\/p>\n With most powder supplements, we look for a formula that dissolves as perfectly as possible. When it comes to mass gainers, though, this is a little more difficult to achieve, as the consistencies are pretty thick and dense. For our recommendations, we suggest using a blender, rather than a standard shaker cup.\u00a0<\/p>\n Formula<\/p>\n We work with a certified nutrition coach during testing in order to find the most effective and safe mass gainer formulas. In our search, we prioritized mass gainers that have more calories than a general protein powder, which tend to hover around 110 or 120 calories per serving. We also look for mass gainers without artificial sweeteners and other additives.<\/p>\n Mixability\u00a0<\/p>\n When preparing a mass gainer shake, we follow the brand\u2019s recommended instructions, ensuring we measure the correct serving size and liquid amount. Special attention is paid to how well the powder blends, since the larger serving sizes can sometimes create gritty textures or stubborn clumps if not properly mixed. To achieve a smooth, enjoyable consistency and avoid unpleasant thickness or chunkiness, we often opt to use a blender for mass gainers, rather than just a shaker bottle, and adjust liquid as needed until the shake is dissolved.<\/p>\n Third-Party Testing<\/p>\n We selected mass gainers that have been third-party tested. Third-party testing ensures independent verification of safety, purity, as well as nutrition label accuracy. This helps to reduce the risk of mislabeling or underdosing. Third-party testing also checks for harmful substances such as heavy metals, pesticides, and more for safety.\u00a0<\/p>\nMass Gainer<\/strong>Calories Per ServingMacro BreakdownSweeteners UsedFlavors<\/tr>\n Transparent Labs Mass Gainer<\/strong><\/a><\/p>\n 770<\/td>\n 110 g carbs, 53 g protein, 15 g fat<\/td>\n Stevia<\/td>\n Chocolate glaze donut, sweet vanilla, chocolate peanut butter<\/td>\n<\/tr>\n Nutricost Mass Gainer<\/strong><\/a><\/p>\n 1,220<\/td>\n 250 g carbs, 50 g protein, 5 g fat<\/td>\n Sucralose<\/td>\n Chocolate peanut butter, cookie n cream, double chocolate<\/td>\n<\/tr>\n Huel Black<\/strong><\/a><\/p>\n 400<\/td>\n 24 g carbs, 40 g protein, 17 g fat<\/td>\n Organic coconut sugar and stevia<\/td>\n Chocolate, banana, strawberry shortcake, vanilla, cookies and cream, and more<\/td>\n<\/tr>\n Crazy Nutrition Mass Gainer<\/strong><\/a><\/p>\n 488<\/td>\n 56 g carbs, 39 g protein, 10 g fat<\/td>\n Sucralose<\/td>\n Chocolate, vanilla<\/td>\n<\/tr>\n Optimum Nutrition Serious Mass<\/strong><\/a><\/p>\n 1,260<\/td>\n 253 g carbs, 50 g protein, 5 g fat<\/td>\n Sucralose<\/td>\n Banana, chocolate, chocolate peanut butter, strawberry, vanilla<\/td>\n<\/tr>\n Transparent Labs Mass Gainer<\/strong><\/a><\/tr>\n \n 770<\/td>\n<\/tr>\n \n 110 g carbs, 53 g protein, 15 g fat<\/td>\n<\/tr>\n \n Stevia<\/td>\n<\/tr>\n \n Chocolate glaze donut, sweet vanilla, chocolate peanut butter<\/td>\n<\/tr>\n Nutricost Mass Gainer<\/strong><\/a><\/tr>\n \n 1,220<\/td>\n<\/tr>\n \n 250 g carbs, 50 g protein, 5 g fat<\/td>\n<\/tr>\n \n Sucralose<\/td>\n<\/tr>\n \n Chocolate peanut butter, cookie n cream, double chocolate<\/td>\n<\/tr>\n Huel Black<\/strong><\/a><\/tr>\n \n 400<\/td>\n<\/tr>\n \n 24 g carbs, 40 g protein, 17 g fat<\/td>\n<\/tr>\n \n Organic coconut sugar and stevia<\/td>\n<\/tr>\n \n Chocolate, banana, strawberry shortcake, vanilla, cookies and cream, and more<\/td>\n<\/tr>\n Crazy Nutrition Mass Gainer<\/strong><\/a><\/tr>\n \n 488<\/td>\n<\/tr>\n \n 56 g carbs, 39 g protein, 10 g fat<\/td>\n<\/tr>\n \n Sucralose<\/td>\n<\/tr>\n \n Chocolate, vanilla<\/td>\n<\/tr>\n Optimum Nutrition Serious Mass<\/strong><\/a><\/tr>\n \n 1,260<\/td>\n<\/tr>\n \n 253 g carbs, 50 g protein, 5 g fat<\/td>\n<\/tr>\n \n Sucralose<\/td>\n<\/tr>\n \n Banana, chocolate, chocolate peanut butter, strawberry, vanilla<\/td>\n<\/tr>\n
