10 Best Protein Powders For Weight Gain in 2026

A single serving delivers 1,280 calories and 52 grams of protein, making it a dense option for anyone who needs a big caloric boost to support weight gain. The blend of whey and casein provides both fast- and slow-digesting proteins, and the added 1 gram of creatine per serving supports strength and power during training. This combination means you get sustained protein delivery without needing to mix in extra supplements.

Each serving delivers 245 grams of carbs alongside 1,280 calories, making this a dense option for those who need substantial fuel. If you’re a hardgainer or an athlete burning through energy quickly, that carb load supports rapid replenishment. But for anyone aiming to keep carbohydrate intake moderate while bulking, this formula may feel heavier than desired.

Over 1,200 calories and 50 grams of protein per two-scoop serving make this a straightforward tool for anyone who struggles to eat enough for steady weight gain. The protein blend supports muscle repair after training, while the added vitamins and minerals help fill nutritional gaps when you’re focused on bulking. This is the kind of shake you reach for when your appetite can’t keep up with your goals, and the customizable shake builder lets you blend with milk, fruits, or peanut butter for extra calories.

The trade-off is the carb load, over 250 grams per serving, which delivers quick energy but might feel heavy if you prefer a lower-carb approach. Compared to Dymatize Super Mass Gainer, which offers 1,280 calories and 52g protein per serving, Serious Mass provides a similar calorie count with a slightly different protein blend. If you’re looking for a no-nonsense mass gainer that covers the basics, this one fits the bill.

Each serving delivers 1,230 calories, 50 grams of protein, and 248 grams of carbs from just three ingredients: pea protein, organic rice protein, and organic tapioca maltodextrin. That simplicity is the whole point here. No artificial sweeteners, no soy, no gluten, no dairy. For vegans or anyone avoiding dairy-based mass gainers, this gives you a clean slate to build shakes around. The NSF certification adds real confidence that what’s on the label is what’s in the tub.

You’re getting only 11 servings from that 8-pound bag, so if you’re drinking a shake daily, you’ll be reordering often. And because it’s unflavored, you’ll need to add fruit, nut butter, or cocoa to make it taste like something. But if you want total control over what goes into your weight-gain shake and prefer a plant-based protein source that’s verified clean, this is the one to grab.

1,250 calories per serving with just three ingredients, that’s the kind of simplicity that makes NAKED Mass stand out in a shelf full of long, unpronounceable lists. You get 50 grams of protein from a fast-release whey and slow-digesting casein blend, plus 252 grams of clean carbs from organic tapioca maltodextrin. The combination of fast and slow proteins means your body gets amino acids over a longer period, which can support muscle recovery after exercise. It’s NSF Certified, so you know exactly what’s in the tub, and with only 5 grams of sugar per serving, you’re not loading up on empty sweets. Reviewers report this is a straightforward way to add calories without artificial ingredients.

It’s unflavored, so you’ll need to blend it with cocoa, peanut butter, or fruit to make it taste like something you’d actually look forward to. That’s a small extra step for the ingredient transparency you get. NAKED Mass comes in an 8-pound container, which is bulky but gives you more servings per buy. If you’re a hard gainer who values clean sourcing over convenience, this one earns its spot at the top of the clean ingredients list.

A 4:1 ratio of carbs to protein means you get steady energy alongside muscle-building support, not just a sugar spike that fades before your next set. With 1200 calories and 50 grams of protein from whey and casein, this is built for the person who genuinely struggles to eat enough throughout the day. It wants a shake that pulls double duty: fueling hard training and helping recovery last. The 10 grams of fiber is a thoughtful addition that keeps things moving, so you are not left feeling sluggish after downing a high-calorie shake.

The trade-off here is that a single serving is a serious commitment to drink. If you are someone who already feels full after a normal meal, this much liquid volume can be a chore rather than a boost. Compared to other mass gainers on the market, BSN True-Mass provides 1200 calories per serving with a 4:1 carb-to-protein ratio, which supports sustained energy rather than a quick carb dump.

With 1,100 calories and 56 grams of protein per serving, this gainer packs serious fuel for anyone trying to add weight without relying on processed fillers. That whole-food approach makes it a smart pick if you want the convenience of a shake but prefer ingredients you can recognize.

Portion control is the challenge: each serving delivers 1,100 calories, which is a big jump for someone just starting to bulk or aiming for modest gains. If you need a more moderate calorie count per scoop, something like Optimum Nutrition Serious Mass Gainer offers a different calorie profile. But if you want a dense, whole-food-based shake that simplifies hitting a high calorie goal, this one earns its spot for ingredient quality.

A single serving delivers 1,500 calories and 60 grams of protein when mixed with skim milk, enough fuel to push past stubborn weight plateaus without needing multiple shakes a day. The added HPLC-tested creatine monohydrate targets ATP replenishment, which can help you grind out an extra rep or two in the gym. That makes it a useful choice for lifters who already know creatine works for them but prefer getting it in their shake instead of a separate powder.

Each serving packs 60 grams of protein and 1,500 calories when mixed with skim milk, making it one of the most calorie-dense mass gainers available. That means you get more fuel per scoop compared to a product like Dymatize Super Mass Gainer, which delivers 1,280 calories per serving. The trade-off is a hefty drink that some might find hard to finish in one sitting, so it’s best for those who want a complete calorie-and-creatine package and don’t mind a denser shake.

With over 1,220 calories and 40 grams of all-whey protein per serving, this mass gainer is built for anyone who struggles to pack on size through food alone. The 250-gram-plus carb blend delivers a high-calorie formula, while the added creatine monohydrate is included in the mix. It’s a straightforward, no-nonsense formula for lifters who want a whey-based option that delivers big numbers without filler proteins.

The 6:1 carb-to-protein ratio leans heavily on carbs, great for hardgainers but less ideal if you’re trying to keep carbs in check. The directions say to mix with water or milk and to combine it with a high-calorie diet and weight training.

With 53 grams of protein and just 6 grams of fat per serving, this mass gainer leans hard into muscle-building without loading you up with extra grease. That high-protein, low-fat ratio makes it a good fit for adding size while keeping your macros clean. The blend of whey concentrate and micellar casein provides a complete amino acid profile to support nitrogen retention and muscle recovery.

The 99 grams of carbs per serving is substantial, fine if you’re training hard and need the energy, but maybe more than you want if you’re watching your carb intake. Compared to other mass gainers on the market, NutraBio keeps the fat lower and the protein higher, making it a leaner choice for steady, controlled weight gain.

Fifty grams of beef protein isolate per serving delivers a concentrated amino acid profile with zero fat and zero sugar. That makes this mass gainer a good option for adding serious calories without extra junk. The lactose-free formula helps if dairy-based powders upset your stomach. The product is formulated for high-speed macronutrient delivery, with proteins and carbohydrates that absorb quickly to support protein and glycogen synthesis, which may aid muscle recovery and growth under ideal conditions.

The carb load is 125 grams per serving, which is a lot, so if you’re someone who prefers a lower-carb approach or a slower energy release, this might feel like overkill. For lifters who want a clean, dairy-free, high-calorie option with fast-digesting protein, this fits the bill.
