10 Best Powders For Gaining Muscle in 2026

1,280 calories and 52 grams of protein per serving make this a heavy hitter for anyone trying to pack on size without spending all day eating. The blend of fast-digesting whey and slow-digesting casein is designed to fuel muscle growth and recovery with sustained protein delivery. That extra gram of creatine per serving is a nice bonus for pushing through those last few reps, especially if you forget to take it separately.

The trade-off is serving size: you get only eight servings per tub, so if you drink one shake daily, that container won’t last two weeks. This product is best suited for people who want a calorie-dense shake and don’t mind restocking frequently.

Over 1,200 calories and 50 grams of protein in a single serving mean this is built for the hardgainer who struggles to eat enough through food alone. The carb load, over 250 grams, helps replenish glycogen stores, fuel workouts, and support sustained energy throughout the day, while the protein blend supports muscle repair and recovery after intense training. This is a calorie-dense shake for anyone focused on packing on size without overthinking the recipe.

Those calories come mostly from carbs, so if you are watching your carbohydrate intake or prefer a leaner gainer, this might feel heavy. It is a straightforward, calorie-dense tool for anyone focused on packing on size without overthinking the recipe.

With 50 grams of protein and 1,250 calories per serving, this mass gainer delivers a high calorie count in a single scoop. What sets it apart is the short ingredient list: just three components, whey, casein, and organic tapioca maltodextrin, with no artificial sweeteners, soy, or gluten. The combination of fast-release whey and slow-digesting casein is designed to support protein synthesis over time, which can help when you’re aiming to add size. If you prioritize knowing exactly what goes into your supplement, this formula keeps things straightforward.

The high carb count of 252 grams per serving is a lot, even for a hard gainer. If you’re watching your carb intake or trying to keep things leaner, that number might feel overwhelming. Naked Mass also comes unflavored, so you’ll need to add milk, fruit, or cocoa to make it taste like something you actually want to drink. But for the person who values ingredient transparency above all else, those small inconveniences are a fair trade.

Sixty grams of protein in a single serving is the kind of number that makes you stop and check the label twice. That’s a serious protein punch for anyone trying to build muscle without choking down five shakes a day. Optimum Nutrition Gold Standard Pro Gainer wraps that protein into a 650-calorie serving with over 80 grams of carbs and less than 8 grams of sugar. That means you get the fuel for recovery without a sugar crash. It’s a smart middle ground for lifters who want a high-protein blend that still keeps the carb source clean and the calorie count manageable for daily use.

At 650 calories per serving, this weight gainer delivers a controlled energy boost rather than the extreme calorie bomb some alternatives provide. Dymatize Super Mass Gainer, for instance, packs 1,280 calories per serving, so if you need a massive surplus, this won’t be your heaviest hitter. But if you prefer a more manageable calorie load that lets you add extra food or milk without overshooting, this blend hits a sweet spot.

The 4:1 carb-to-protein ratio means 1200 calories and 50 grams of protein from a blend of whey and casein per serving. That fiber content, 8 grams per serving, is part of the formula. This product is built for someone who needs serious fuel to recover from intense training.

At 1,200 calories per serving, this is the highest-calorie mass gainer BSN makes, so you’re getting a serious energy dose in a single shake. That intensity comes with a trade-off: the tub holds just 15 servings, meaning you’ll burn through it faster than some other options. The container weighs 10.4 pounds, which makes it a home-use item rather than something you’d toss in a gym bag. If you want a precise 4:1 carb-to-protein split and don’t mind fewer servings per tub, this delivers exactly that ratio.

With 53 grams of grass-fed whey protein and a full 3-gram dose of creatine monohydrate in each serving, this mass gainer packs serious muscle-building power into a cleaner formula than most. The protein comes from grass-fed whey concentrate, which provides a complete amino acid profile to support muscle protein synthesis and recovery, while the 110 grams of slow-digesting carbs help fuel workouts and stabilize energy. It’s a great fit if you want a high-calorie shake that skips artificial sweeteners and fillers, and the third-party testing adds peace of mind for purity.

Each serving delivers 770 calories, which is lower than bulkier options like the Dymatize Super Mass Gainer’s 1280 calories. If you’re a hard-gainer needing a massive caloric surplus in fewer shakes, you might find yourself blending two servings or adding extra ingredients. The 15-serving tub also means you’ll reorder more often than with larger containers. But for someone who values clean ingredients and a built-in creatine boost over sheer calorie density, this is a smart, straightforward choice.

With over 1,000 calories and 60 grams of protein in each serving, this mass gainer delivers a dense calorie load for anyone who has trouble eating enough to gain weight. The formula includes micellar casein, creatine, and glutamine as listed ingredients. This shake is designed for lifters who want a straightforward way to add size, with no subtlety about the calorie surplus.

The trade-off is the carbohydrate load, 180 grams per serving can feel heavy if your daily activity doesn’t match the calorie demand. Compared to Dymatize Super Mass Gainer, which sits at 1,280 calories with 52 grams of protein, Ronnie Coleman King Mass XL offers more protein and a bigger tub, but it’s not a subtle tool. Best for the lifter who knows they need a calorie surplus and wants one big, effective shake to get there.

With 1020 calories and a four-source protein blend that mixes whey concentrate, whey isolate, calcium caseinate, and egg white albumin, this powder is built for the hardgainer who has trouble keeping weight on. The fast-release proteins hit your muscles right after a workout, while the casein and egg white keep feeding them for hours. That makes it a strong option for anyone who wants around-the-clock muscle support without chugging shakes every two hours.

The serving size requires four scoops (250g) per drink, so the 10.45-pound tub provides 18 servings. That means it will be used up faster than some higher-calorie powders that deliver more calories per serving. If you prefer a multi-source protein blend with whey concentrate, whey isolate, calcium caseinate, and egg white albumin for both fast and slow release, this formula offers a mix of protein types that can support muscle recovery over a longer window.

The 1,100 calories per serving make this a serious tool for anyone who finds it hard to eat enough to gain weight. What sets it apart is the whole-food ingredient list: barley, sweet potato, rolled oats, avocado, coconut oil, flaxseed, pumpkin seed, and sunflower oil, so you’re not just downing processed powder. This is for the person who wants their mass gainer to feel a little more like real food, with a protein blend of whey isolate, concentrate, and casein that gives 56 grams per serving.

The trade-off is serving count: a 5-pound pouch gives only 16 servings, which means you’ll be reordering sooner than with bigger tubs like Optimum Nutrition Serious Mass (12 pounds). That smaller size works if you’re testing the waters or traveling, but for daily use it adds up. If whole-food ingredients matter to you and you don’t mind a shorter supply, this is a thoughtful pick. If you want maximum servings per container, look at the Serious Mass instead.

A single six-scoop serving mixed with two cups of skim milk delivers 1,500 calories, making it a practical tool for anyone who finds it difficult to consume enough solid food to support rapid weight gain. The same serving provides 60 grams of protein along with 304 grams of easily digestible carbohydrates, which helps replenish glycogen stores after training. This approach eliminates the need to track down separate creatine or BCAAs, since each scoop already contains HPLC-tested creatine monohydrate and over 13 grams of branched-chain amino acids. For lifters focused on building mass efficiently, this all-in-one formula simplifies the process of meeting daily calorie and protein targets.

Each serving is six scoops, and the instructions call for mixing with two cups of skim milk, which means a fairly large shake. That can feel like a lot to get down if you are not used to big liquid meals, and the total calorie count may overshoot your needs if you are aiming for a moderate surplus. Compared to a product like Optimum Nutrition Serious Mass Gainer, which comes in a 12-pound tub and offers a slightly lower calorie density, MuscleTech’s High Protein Mass Gainer is more concentrated, so you get more fuel per shake, but less flexibility to dial in a smaller serving.
