10 Best Protein Powders For Putting On Weight in 2026

With 1,280 calories and 52 grams of protein per serving, this mass gainer provides a high calorie and protein intake in a single shake. The blend of whey and casein proteins offers both fast and slow digestion, which can support muscle growth and recovery as stated in the product features. This makes it a practical choice for anyone looking to increase their daily calorie and protein intake without preparing multiple meals.

The trade-off is the carb load: 245 grams per serving is high. If you prefer a gainer with fewer carbs, the Optimum Nutrition Serious Mass Gainer offers a different macronutrient profile. For someone who wants a high-calorie, high-protein shake with added creatine and vitamins, this product delivers those nutrients in one serving. Note that the container provides 8 servings, so it may not last long if used daily.

With 1,200 calories per two-scoop serving, this is a serious tool for anyone who struggles to eat enough to gain weight. The 50 grams of blended protein, plus added creatine, glutamine, and BCAAs, gives your muscles a broad recovery boost after hard training. It’s the kind of shake you reach for when your appetite just can’t keep up with your goals, and the extra vitamins and minerals help fill nutritional gaps that often come with a high-calorie diet.

The carb load here is significant: over 250 grams per serving means this is a heavy, thick shake that can feel like a meal in itself. If you prefer a leaner profile, the Dymatize Super Mass Gainer offers a similar calorie count but with slightly fewer carbs and more protein per scoop. For anyone who wants a classic, all-in-one mass gainer that leaves little room for guesswork, this tub delivers exactly what it promises.

A single serving delivers 1,360 calories, 50 grams of protein, and 251 grams of carbs, enough fuel to turn a hard-gainer’s day around without needing a second scoop. That’s the kind of density that makes bulking feel less like a chore and more like a strategy. NAKED Mass uses five ingredients: whey, casein, organic tapioca maltodextrin, organic coconut sugar, and organic raw cacao. It contains no artificial sweeteners, no soy, no gluten, and is NSF Certified for purity and safety. For someone who wants clean fuel without the mystery chemicals, this is the one to reach for.

The 1,360 calories per serving are a serious calorie load, so if your stomach isn’t used to that volume, you’ll want to start with half a scoop and work up. Compared to Dymatize Super Mass Gainer’s 1,280 calories and 245g carbs, NAKED delivers more of both. The 8-pound bag works well for kitchen counter storage but is too bulky for a gym bag. If you prioritize simple ingredients and certified purity over portability, this mass gainer fits the bill.

Each serving delivers 1,230 calories, 50 grams of protein, and 248 grams of complex carbs from just three ingredients: pea protein, organic rice protein, and organic tapioca maltodextrin. No artificial sweeteners, no soy, no dairy, and no gluten. For anyone following a vegan diet or avoiding common allergens, this is about as clean as a high-calorie shake gets. The NSF certification adds a layer of trust that what’s on the label is exactly what’s in the bag.

Each serving delivers 1,230 calories, 50g of protein, and 248g of complex carbs from just three ingredients: pea protein, organic rice protein, and organic tapioca maltodextrin. That means you get a clean, plant-based calorie load without artificial sweeteners, colors, or flavors. It’s also NSF Certified for purity, so you know what’s on the label is what’s in the tub. The trade-off is that it’s unflavored, so you’ll need to add fruit, nut butter, or a splash of plant milk to make it taste like something. That also means you control the sweetness and avoid the cloying fake flavors some gainers lean on. If you want a straightforward, allergen-friendly way to pack on mass without mystery ingredients, this is it.

A single serving of this powder packs 1,100 calories and 56 grams of protein, which means you can hit a serious calorie surplus without spending all day chewing. That makes it a strong fit for people who find it hard to get enough calories from whole food to gain weight, especially if you want ingredients that look like they came from a grocery list rather than a chemistry lab. The blend of barley, sweet potato, rolled oats, avocado, coconut oil, flaxseed, pumpkin seed, and sunflower oil gives it a whole-food profile that feels more like a meal replacement than a typical mass gainer. The whey isolate, concentrate, and casein combination also spreads protein release over a few hours, which can help with recovery and fullness between meals.

The trade-off here is portion control and flavor commitment. With 16 servings per pouch, you will go through it faster than some bulkier options, so if you plan to use it daily, you will want to stock up. Compared to the Dymatize Super Mass Gainer, which offers 1,280 calories and 52 grams of protein per serving, Mutant Mass Extreme Gainer leans harder on recognizable food sources rather than a simpler carb-and-protein mix. That whole-food approach is great if you prefer ingredients you can pronounce, and the triple chocolate flavor delivers a rich taste that many will enjoy.

With 60 grams of protein and 1,500 calories per serving when mixed with skim milk, this is one of the most calorie-dense mass gainers you can grab. It’s built for someone who wants serious weight gain without overthinking the math, especially if strength and muscle size are the main goals. The 6.3 grams of L-leucine and over 13 grams of BCAAs also support muscle repair, making each scoop work harder for you.

Each serving requires six scoops, which empties the tub faster than some competitors. Dymatize Super Mass Gainer lists 52 grams of protein and 1,280 calories (per unspecified amount), while this MuscleTech version provides more calories and includes creatine, but it demands a bigger commitment per shake. If you’re okay with a heavier carb load and want that creatine boost built right in, this is a straightforward choice, just be ready to mix with milk to hit those top numbers.

770 calories per serving from oat flour, organic tapioca maltodextrin, and sweet potato powder means this mass gainer leans on whole food sources rather than cheap sugars. That makes it a cleaner option for anyone trying to add weight without feeling like they’re drinking dessert. The 53 grams of grass-fed whey deliver a complete amino acid profile, and the added 3 grams of creatine monohydrate support both strength gains and recovery. If you want a high-calorie shake that still respects ingredient quality, this one fits the bill nicely.

The carb load here is substantial: 110 grams per serving, so if you’re sensitive to heavy carbs or prefer a lower-carb approach to gaining weight, this might feel like too much. Dymatize Super Mass Gainer delivers 1,280 calories per serving, while Transparent Labs offers a different calorie density. For someone who values transparency and real-food ingredients over sheer calorie density, this is a strong pick.

With 690 calories and a deliberate 2:1 carb-to-protein ratio, this gainer aims for steady, manageable mass rather than a calorie bomb. The 50g of protein comes from whey protein concentrate, calcium caseinate, milk protein isolate, whey protein isolate, micellar casein, hydrolyzed whey protein, and egg whites. That gives your body both fast and slow-digesting proteins over several hours. It’s a smart pick if you want to add weight without feeling like you’re force-feeding yourself a massive shake every time. The MCT fats round out the nutrition, and the flavor tech promises a thick, dessert-like drink that actually makes you look forward to your post-workout refuel.

At 690 calories per serving, serious hardgainers might want more per shake compared to something like Dymatize Super Mass Gainer, which packs nearly double the calories. But that’s also the point: BSN True-Mass gives you room to stack two servings without going overboard, or to add your own peanut butter and milk. It’s a balanced approach for someone who wants quality protein variety and a reasonable calorie boost, not just a sugar rush. Just know that if you’re dairy-sensitive, the blend of whey, casein, and milk protein isolates won’t work for you.

With over 1,220 calories and 250g of carbohydrates in a single serving, this is a serious tool for people who find it hard to get enough calories to gain weight. The 6:1 carb-to-protein ratio means a high proportion of carbs relative to protein, and the 40g of all-whey protein plus creatine monohydrate are included per the label. It’s a calorie-dense shake designed for those who want a straightforward mass gainer.

This is a carb-forward formula, so if you prefer a leaner gainer with more protein relative to carbs, something like Dymatize Super Mass Gainer (with 52g protein and 245g carbs) might fit better. But for someone who needs a high-calorie shake and can handle mixing it with 18-20 oz of liquid, Rule 1 provides the numbers stated on the label. Just be ready to combine it with a high-calorie diet and consistent training.

For anyone watching their sugar intake, the sweetener choice here is a real win. The formula relies on stevia leaf extract for sweetness and keeps added sugar down to just 2g per serving. That means you get a clean-tasting shake without the blood sugar spike or artificial aftertaste. Many mass gainers load up on sugar to mask their ingredient profile, but this one skips the artificial colors, dyes, and fillers entirely. It also happens to be gluten free, so it fits a broader range of dietary needs without sacrificing flavor or texture.

The dairy protein blend means it won’t work for those with lactose sensitivities. Dymatize Super Mass Gainer delivers 1,280 calories per serving, while this is a lower-calorie option. It offers a moderate calorie count for steady weight gain.
